Let me chime in here...

I'm heavily agreeing with Milian here -- don't just blindly plaster QObject::deleteLater calls just everywhere. They make it even harder to debug the application.

Anyway, about the actual bug you're trying to fix: 
- Is it the same backtrace as in https://bugs.kde.org/show_bug.cgi?id=338829?
- If so, please try to make sure you also get line numbers in the backtrace (currently it's quite useless)
- Run KDevelop through valgrind (should be available on OSX) or some XCode memory analyzer, provide the dump here after the crash happened. Check why/where qt_mac_getTargetForMouseEvent fails.

At any rate, please try to find the real issue first.

I had another of those crashes after heavier-than-usual perusal of the toolview, despite the previous patch. The attached patch replaces all `delete`s of `QObject` derived class instances with `deleteLater()`.
