[SOLVED] Canon CQue CUPS job status=stopped "Filter failed"

I love mga5 
It manages both hibernate and suspend on thinkpad R61 and T61, which fail for both mga3,4 and fedora 20.
It also do that amazingly quick and seem snappy overall.
So I am switching two production systems to mga5 already
I have just one problem so far: printing (to network attached printer) i get satus:
stopped
"Filter failed"
Any idea what i should check or try?
Where is a log?
http://localhost:631/admin/log/error_log just gives "Not Found"
I followed the same procedure i described here and was working for same printer on mga2,3,4 and fedora:
