Bug 219147

Application: kdevelop (3.9.95 (using KDevPlatform 0.9.95))
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
Hi,
Kdevelop always crashes when I try to load two files.
The first one is opened without any problem while the app crashes when loading the second one.

Kubuntu kde 4.4 beta 1
The files are on a NFS directory

Thanks a lot !

The crash can be reproduced everytime.

Application: KDevelop (kdevelop), signal: Aborted
