Sentry Crash Report:

Description RJVB 2017-03-26 10:16:46 UTC 
Application: kdevelop5 (5.1.0)
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.9.8-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 crash happens when I exit KDevelop with the PathReview plugin still open, after uploading the diff to Phabricator using the Purpose plugin.

Possibly related to bug 376835 (I'd have attached to that report if DrKonqi would have let me).

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop5), signal: Segmentation fault

Crash deep in Qt (qtdeclarative), no trace of KDevelop:

Very likely an upstream issues, there are some known problems with crashes on destruction inside qtdeclarative.

Might need to wait for Qt 5.9.0.

Ergo: not resolved ;)

While I agree that this happens deep in Qt it may be because of something KDevelop does wrong (or doesn't do), no? In this case I'm thinking of a reference to the Purpose plugin that gets discarded appropriately when you close the PatchReview toolview but not when you quit before closing that toolview. Could be as simple as unloading the Purpose plugin before all references are discarded.

Aleix's turf, I presume.
