Description RJVB 2018-04-13 13:01:18 UTC

Application: kdevelop (5.2.1-88-gf5e79d3876)
 (Compiled from sources)
Qt Version: 5.9.4
Frameworks Version: 5.42.0
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

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

I quit a largish session (holds the KDevelop project, plus a small project). Both projects were unloaded successfully AFAICT, and then I got

QReadWriteLock: destroying locked QReadWriteLock

followed by DrKonqi

I'm currently running #8430d3058f92725b4e6b7d85d8d68550ce12ee79 from the 5.2 branch.

A freak incident?
