--- Comment #1 from Harald Judt <hjudt at xfce.org> ---
I am not sure, but from your backtraces it looks like the same as 10596. I will
resolve this one as duplicate and reopen the original. You might want to add
your mail address to CC there.

I haven't experienced this yet, and it looks like it will be hard to trace. But
as some comments in 10596 state, this seems like some sort of memory corruption
(trying to access already freed variables etc., or maybe some loop that causes
the stack to explode). Without steps to reproduce, I do not know how to track
this. So, some suggestions...

1) Which glib version do you use? For comparison, I have installed 2.42.2 here.
Do you see any suspicious rise in memory consumption when this happens?

2) What could help is if you added debugging statements in thunar-file.c, like:

http://git.xfce.org/xfce/thunar/tree/thunar/thunar-file.c#n651

gchar *p = g_file_get_path (path);
g_print ("thunar_file_monitor_update: %s\n", p);
g_free (p);

To the beginning of the function. Similar to the folder monitor function:
http://git.xfce.org/xfce/thunar/tree/thunar/thunar-folder.c#n706

Of course, do not forget to free the gchar variable or it will be a source of a
leak itself.

With these in place, you might get a starting point to trace it.

3) Since you seem to be able to reproduce it, bisecting this to determine the
first bad commit could help with finding the cause(s). If you have never done
this, searching for "git bisect" will certainly turn up lots of tutorials.
Using "DESTDIR=/install/dir/of/your/choice make install" and launching thunar
from there will make this easy, just don't forget to kill any running thunar
daemon.
