Application that crashed: kdevelop
Version of the application: 3.9.95 (using KDevPlatform 0.9.95)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
To duplicate:
1. Open kdevelop with a split view already open (maybe enough just to open a split view)
2. Close the split view
3. Press Ctrl+Tab: causes immediate crash

I did see a couple of similar bug reports, but comparing stack traces they weren't the same.

Thanks!
