kdevelop exitting on its own

Sat Oct 18 23:36:58 BST 2014

On both my Linux and my OS X systems I've noticed that KDevelop 4.7.0 and 4.7.60 have an irregular habit of exitting after completing the parse-on-open of the projects in the session I started with. This happens regardless of whether I'm doing something in KDevelop or elsewhere.
It's been suggested to set a breakpoint in KDevelop::MainWindow::~MainWindow but hasn't yet proved productive (rather the contrary; starting kdevelop under a debugger take a lot of patience on the systems I have at my disposal). 

So I added a qDebug output of kBackTrace() in KDevelop::MainWindow::~MainWindow, assuming I'd be able to get some idea of where the exit request came from when it happens.

Turns out KDevelop exits without calling this MainWindow destructor:

That's a session in which I have 4 projects, for kdepim and kdepimlibs 4.12.5 and 4.13.3 . Normally things work normally when I relaunch the session, but this time:

3rd time was a charm: here's the output from a session that completed the parsing phase and let *me* quit the application personally:

Is there any chance that this issue might be related to the use of non-killable CMakeImportJobs?

Thanks,
