Application: kate (3.6.5)
KDE Platform Version: 4.6.5 (4.6.5) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.35-gentoo-r15 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I have a couple VMWare Fusion VMs on a host-only network that all share their root drives with each other over NFS. I was opening to browse a CentOS 5 VM's /usr/lib folder with Kate on my Gentoo VM. I have done similiar things in the past and not had issue. The only thing special I can think of about this operation is the size of the directory listing in /usr/lib is much larger than most directories and perhaps a timeout expires? Not sure.

The crash can be reproduced some of the time.

-- Backtrace:
