Thunar also crashed for me when trying to rename a file. Crash happened after the file was successfully renamed.

Managed to get this crash while decompressing files
extracted .tar.bz2
what why did it put a (2) at the end
try it again
open it back up
looks like it never refreshed and showed the 1st file of the same name
