Description Torbjörn K. 2012-11-09 14:34:40 UTC 
Application: kdevelop (4.4.60)
KDE Platform Version: 4.8.5 (4.8.5) "release 521"
Qt Version: 4.8.3
Operating System: Linux 3.4.6-2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Started clean new session and imported a simple CMake project with multiple targets without any KDevelop project file/folder. The root folder (e.g. make all) was added to the current build set.
After building, I added/appended one of the single targets to the build set (left the make all target in there).
Then I hit "prune configuration" and got a error message ('Process Error') :
$HOME/projects/[ProjectName]/build/[NewlyAddedTarget]

(where [ProjectName] and [NewlyAddedTarget] are substituted)

On clicking "OK", KDevelop crashed with a segmentation fault.

The build folder was empty, when the error message appeared, thus pruning the initial target succeeded, but KDevelop wasn't able to prune the second target after it already had been erased.

In case the newly added target is prepended to the build set, the build folder gets pruned as well, though the error message reads '$HOME/projects/[ProjectName]/build/cmake_install.cmake'.


- Custom settings of the application:
KDevplatform and KDevelop compiled from current git master.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 3 Milian Wolff 2012-11-09 22:03:32 UTC 
Git commit cac127eb0f4514734ab6469e7244d4ea0a6cf1a7 by Milian Wolff.
Committed on 09/11/2012 at 22:57.
Pushed by mwolff into branch 'master'.

Do not create multiple configure or prune jobs for the same project.

That is not required and just wasted time when running configure
or shows stupid error messages when pruning.

Comment 4 Milian Wolff 2012-11-09 22:03:32 UTC 
Git commit 601bbfe454b72dbf5407d6ad4516ae0b8a0983c0 by Milian Wolff.
Committed on 09/11/2012 at 22:41.
Pushed by mwolff into branch 'master'.

Don't use nested eventloop to prevent random crashes.

We now use the much more verbose KMessageBox::createKMessageBox
API with the NoExec option to show the job error. This won't use a
nested event loop and thus prevents random crashes.
