Mageia forum

Hi,

I'm having an issue for a while now where Nautilus file manager crashes on load. I've tried starting it from terminal with just "nautilus", but I get no info from terminal other than "segmentation fault" (literally).

How can I get down to exactly what is causing it, either that or set a different file manager to be default in Gnome Classic? I've searched through Gnome Classic and Gnome 3 (shell) both, reset the ~/.config/nautilus and ~/.config/nautilus-actions folders both twice to no avail. For the interim, until this is resolved, I'm using Dolphin, starting it manually, for a file manager in Gnome.

The main problem is when it crashes, I lose all of my desktop icons, the works.

Fully updated here, on kernel-netbook, Mageia 2.

Thanks.

Does it happen with a new user?

Yes, so far. I'm going to try another one, though, to be completely sure.

Edit: Yep, it sure does. I'd like to know how I can run a debug backtrace on this. I have debug repos installed, debug packages installed. I've just forgotten how to use them.

You should take a look at https://wiki.mageia.org/en/Debugging_software_crashes

OK, yeah, I looked at the Gentoo page, and got it.

Are there any other options/arguments needed that I should be using here? I'm thinking that got it? Thanks.

Interestingly, alacarte has also been crashing since Nautilus started crashing. However, I don't know how to resolve this:

Well, for nautilus, you missed the most important point, which is to run "bt full" after you received the segfault, so that all the backtrace information is collected.

Alacarte can't be used for comparison, as it is still broken on Mageia 2: https://bugs.mageia.org/show_bug.cgi?id=2911

OK, I'll run that tomorrow; time for sleep now. Thanks.

Edit: Actually, I just went ahead and did it. The backtrace2.log hosed on me; I thought it would over-write one already there, but it didn't. At any rate, this contains everything done anyway, straight from terminal (and oops, I forgot to do "set logging off" at the end there):

I'm wondering, do I need to file a bug, or is this something else? I can't make heads or tails out of the gdb. Thanks.

Please try again without that dropbox module.

You may also want to have a look at the MAQeia for dropbox:
viewtopic.php?f=36&t=3602
As i don't use dropbox myself, can't really help you further with that ...
But it seems if you're missing some dependencies for dropbox, it will segfault, doesn't matter if under KDE or GNOME.

You mean it will segfault Nautilus, or itself? Dropbox in of itself runs fine here, in both KDE and Gnome.

Ah, wait, I see. Using nautilus-dropbox in KDE can cause it to crash... but it isn't in KDE. Strange.

I'll try that.

Well, whatever it is, it's not nautilus-dropbox. I not only took it out of startup, but also uninstalled it completely, and did not install kfilebox or anything. Nautilus still crashes.

I've updated the pastebin. Scroll down to "Without nautilus-dropbox": http://pastebin.ca/2339565

Then you should open a bugreport against Nautilus and attach the backtrace.

Oh boy. This is opening up a ball of wax.
I've just come across Bug #5163, and I have an NFS share mounted. The problem is, I can't get it umounted to see if that's the problem. It keeps saying "device is busy", both in terminal and in mcc when I try to umount it, when I'm not even using it ATM. It's not doing anything on the server, either.

Edit: Never mind. I just umounted it on the server side.

Edit 2: I umounted the NFS share on the server side, and re-created it as a samba share. This, in turn, allowed me to have it umounted on the netbook side, and I did not add it back as a samba server yet on it. Nautilus is working fine. I've opened it several times in Gnome, with no ill effects. It has not crashed.

I'm going to add the samba server back to it, and see how it does. Stay tuned.

The problem is that the netbook isn't finding it as a samba share. I'm going to have to wait until the server admin is home from work, and see what I need to do. At least I know that loading an NFS share is the problem with Nautilus crashing. I just wanted to see if samba would do the same thing on this particular share, but it's not in the cards right now. I'll report on the bug nonetheless.

Edit: At any rate, since the bug is commented on now, should I mark this as solved, since the thing I really wanted to know was how to find the issue, and that was answered? Solve as "referred to bugzilla bug #5163" ? I think I should, as it's in their hands now. Thank you for all of your help!
