-- Information about the crash:
Started KDevelop again after the crash in 321266. Clicked the Project tab-thingie on the left. Opened the build configuration window, but it had no content except for the buttons at the bottom. Tried again, but with the same results. Right-clicked the Build button at the top of the window. Clicked the first alternative (build). KDevelop crashed.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
