Description RJVB 2017-09-14 21:20:32 UTC 
Application: kdevelop (5.1.40)
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.35.0
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

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

1. open contextmenu in modified file (repeat until the "Review Patch" entry shows)
2. choose "Review Patch"
3. leave the patch review mode with the dedicated button
4. use the contextmenu to activate git/commit
5. Fill in this report.

- Unusual behaviour I noticed:

- the "Review Patch" context menu entry isn't present systematically
- the "Review Patch" mode doesn't show a diff but the file itself
- after leaving this view, the file now shows the project name prepended in titlebar and the open document drop-down menu
- after quitting KDevelop (without closing the document) it will no longer be open

This happens on Mac, but not when using the XCB qpa (i.e. X11 mode). It reminds of crashes we've seen in the past when pending mouse events were delivered to an already deleted object because `delete` was used instead of `deleteLater()`.

The crash can be reproduced every time.
