Version:           3.9.95 (using KDE 4.3.1)
OS:                Linux
Installed from:    Unlisted Binary Package

I am reliably getting the following:

1. Open a CMake based project in KDevelop
2. Edit the CMakeLists.txt belonging to this project externally (for example in KWrite)
3. Wait for KDevelop to notice the change and automatically reload the project
5. Click on Project->Build
6. Crash

I noticed that I can avoid the crash and successfully build by adding the following step 4:

4. Click on the project in the "Projects" window in the left dock

This appears similar to bug 186702 but that one has been closed as fixed a while ago while this crash occurs with the most recent beta.

The system is Arch Linux x86_64.
