Description Eric 2014-03-16 19:12:15 CET 
Steps to reproduce the crash :
- Lauch Thunar
- Wait for it to crash or use it, but you may encounter loss of data if it segfaults.

Here is a backtrace :

Comment 2 Andrzej editbugs 2014-03-17 20:58:48 CET 
Just a guess, can you post/check a result of:
$ ldd `which thunar`

Last time I have seen "weird" thunar crashes they were caused by two different versions of libraries (afair some plugins) linked together. Watch for any suspicious path differences.

Comment 5 Eric 2014-03-24 17:54:16 CET 
After a week of research, the segfault was caused by my conky.

Changing my conky files made just the bug disappear.
