Additional info:

Reason for closing:  Fixed
Additional comments about closing:  Should be completely fixed in thunar 1.6.11-2.

Is this always reproducible on the first try? Might be a duplicate of  FS#46657 .

Edit: Found a Debian report that links the bug to glib 2.46, which is similar to the report I've filed upstream. [1]

This is reproducible. Every time I drag an image from the desktop into Thunar ... poof! This time I tried a JPeg.

However, this was not happening in a VM I have at work. It's a similar set up with XFCE, but it's not using the LTS kernel and its under VMWare.

Just had this happen again.

BTW the previous message mentions LTS - I'm no longer using that.
Comment by IMBJR (IMBJR) - Thursday, 17 December 2015, 17:49 GMT
Oof. Now I'm getting random crashes on renaming .m4a files. Thunar merely reports at the command line:

Segmentation fault (core dumped)

I'm running a strace on thunar, but it's decided to no longer crash.

Please backport this patch [1], it may help.

Comment by Evangelos Foutras (foutrelis) - Monday, 21 December 2015, 19:20 GMT
I have tried that patch and it does not help.

Edit: I mean it doesn't fix the crashes when renaming files ( FS#46657 ); I haven't had any crashes when using drag-n-drop so I can't comment on that.
Comment by Thomas (radioactiveman) - Monday, 21 December 2015, 19:36 GMT
I think it would not hurt adding it anyway. It is an official patch and fixes a crash.
Comment by IMBJR (IMBJR) - Tuesday, 22 December 2015, 17:13 GMT
The patch does not resolve the drag-and-drop crash.

AMD 6510 using radeon driver and I can reproduce the issue aroun half the times I drag, I tried a torrent file and it crash the 2,4 and 5 time I tried it.

but I noticed that disabling rendering-fancy-stuff in xfce still got the same result but a little less often.

The drag-and-drop crash (which is distinct from the renaming crash,  FS#46657 ) is still present in upstream Git master.

Here is a fix that works for me:

Please consider including this patch in the Arch Linux package. No XFCE developer has made any comment on the upstream bug since February, so waiting for an upstream fix in this case may not be a good plan.

John, with Git master you mean thunar-git 1.6.10.r140.g6b51ff3-1?

This version still crashes sometimes when renaming a file.

Hey Evangelos,

maybe you want to add the patches from ?
