Description RJVB 2016-09-23 12:25:32 UTC 
Application: kdevelop5 (5.0.1)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.5.7-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:

This was a session that I had launched only to check a few aspects of the CMake manager's build dir settings. After telling it to exit it remained stuck as shown in the backtrace, consuming close to 100% CPU.

This has been discussed before. In a debug build the ASSERTS will provoke an abort, but now that KDevelop5 has seen 2 release versions already anomalies in deleteItem() should also be handled (as elegantly as possible) in release builds.

Apparently currentIndex should never become 0. What would be the side-effects of returning early from deleteItem(), i.e.

        //If this assertion triggers, the deleted item was not registered under the given hash
        Q_ASSERT(currentIndex);
        if (!currentIndex) {
            return;
        }

It seems deleteItem() has no business trying to delete an item that's not registered under the current hash, but not doing anything may mean we'll end up in slightly larger closed loop, calling deleteItem() on the same item indefinetely?

The crash can be reproduced sometimes.
