[Pkg-xfce-devel] Bug#805574: thunar: renaming leads to segfault
in some cases when I rename several files (each file individually), I experience frequent segfaults.
The last file that was renamed when the segfault occured ends up with the correct name but annoyingly the thunar window is closed.
* What led up to the situation?
Renaming a file after at least one file was renamed previously. It can be the same file.
* What exactly did you do (or not do) that was effective (or ineffective)?
* (optional) create a new folder with a (new, empty) file "test"
* open this folder with thunar
* select file, choose rename (F2 or Mouse)
* rename e.g. to "asdt" by selecting first 3 letters ("tes") and typing "asd", hit Enter
* rename again to "asdft" by selecting first 3 letters ("asd") and typing "asdf", then hit Enter -> segfault
Mostly, the segfault can be reproduced when selected letters/strings are replaced or deleted. It seems that it occurs more often when the new string has different length (also shorter strings work sometimes) than the replaced string. I couldn't nail it down completely...
If you just insert the "f" in the example above, it won't do the trick - at least it didn't when I tested it once.
I tried to get a backtrace with gdb (my first time to use it, though), following this:
The segfaults occured much less frequent (only once) - I could find a reference to libc.so.6. (I don't remember the full message, something with "libc.so.6" and "SIGSEGV")
After installing the libc6-dbg package, however, I could not get thunar to crash again (when running it through gdb). Maybe the real culprit is not thunar but I'm stuck at this point with my investigations...
* What was the outcome of this action?
Thunar exited, printing a "segmentation fault". The file was renamed correctly.
Thanks for looking into this issue!
