--- Comment #14 from ajscholl <jonas.scholl at gmx.de> ---
I think I am hitting the same issue. I created two directories, /tmp/a and
/tmp/b, and two empty files with the same name in them. Then I copied the file
from /tmp/b to /tmp/a. As soon as I tell thunar to overwrite the file, it
crashes. I think this is the same bug because my stack trace is looking
similar.

I did compile thunar and gtk2 with debug symbols and got the following stack
trace:

Core was generated by `./thunar-bin'.

Looks like icon points to... data explicitly set to 0xaa. So maybe someone
forgot to write actual data to it?
