Application that crashed: kdevelop
Version of the application: 3.9.96 (using KDevPlatform 0.9.96)
KDE Version: 4.3.2 (KDE 4.3.2)
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:
Using SVN version from Nov 4, 2009. Kdevelop crashed when pressing the F8 key (build project). The last few lines on konsole were:

Calling appendChild() on a null node does nothing.
Calling appendChild() on a null node does nothing.
