Can reproduce here, "Complements" is apparently a not-quite-correct translation of Plugins. 

Apparently the documentationcontroller (or some of its parts) keep references to the documentation plugins, but don't hook into the plugin loading/unloading notifications. And hence they crash trying to access an already deleted plugin pointer.

    Make the Documentation view aware of documentation plugins being hot-(un)pluged instead of crashing.

New crash information added by DrKonqi

kdevelop (4.0.2 (using KDevPlatform 1.0.2)) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:

Closing KDevelop makes the program crash in error.  This happens on Ubuntu 10.04 after a fresh install of KDevelop from the repo.

kdevelop (4.0.2 (using KDevPlatform 1.0.2)) on KDE Platform 4.5.5 (KDE 4.5.5) using Qt 4.7.0

- What I was doing when the application crashed:

Segmentation fault on exit (ubuntu 10.10).
I just clicked on the "X" button and, after the main window close, the "crash report window" opened up.
I did it three times. I was using KDevelop for the first time (just some trial executions).
