Open file crashes in Qt apps

[oldefortran]

I have qt 4.3.1 installed, and when trying to open a file in any qt based program, it starts to list files in my home directory, and then it suddely craches.
I have 2086 files in my homedir.

Here is the output from Lyx that crashed. I got similar result with a program called qdevelop.
