Bug 177873

Version:           1.1.80 (using Devel)
Compiler:          gcc version 4.3.2 (Debian 4.3.2-1) 
OS:                Linux
Installed from:    Compiled sources

I have this crash sometimes. It is random and I can't reproduce it reliably, but I've seen it already two times since 4.2 beta1. This particular backtrace I am posting was generated while deleting a directory. The other time I got this was when I was moving a directory to another place using split view and drag n' drop. It seems similar to the backtrace in bug 177795 but I am not sure if it is a duplicate.
