Application that crashed: kdevelop
Version of the application: 3.9.96 (using KDevPlatform 0.9.96)
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I've created a new header file and moved a structure form a different h to this one. Probably a problem with the indexer.
