Description RJVB 2017-09-25 20:08:14 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 a Qt-based project
2. hover mouse over a known Qt class like QString
3. wait for the code context browser popup
4. click on "Show documentation for [QString]"

- Unusual behaviour I noticed:
The documentation toolview enables itself. Rendering starts but DrKonqi takes over after a black rectangle appears below the 1st page headers. This could just be an interrupted painting operation.

- Custom settings of the application:
The CMake and manpage plugins are disabled to avoid getting unwanted documentation windows on startup or coming out of the pathreview plugin; the documentation toolview is not on any toolbar either. Documentation viewing should be handled by a dedicated application and not burden an already (top)heavy IDE.

Ideally the "Show documentation for X" link shouldn't be shown if the documentation toolview is disabled. Alternatively, this link should open the documentation in an external browser.

The crash can be reproduced every time.

> Documentation viewing should be handled by a dedicated application and not burden an already (top)heavy IDE.

Please stop grumbling about this on every available medium (mailing list, review board, now bug tracker, ...). It isn't helpful -- it's just adding noise to your reports. Being able to view documentation inline is and continues to be an integral part of what an IDE has to offer.


Having said that, thanks for the detailed bug report. The crash should be fixed of course -- the documentation toolview should be properly initialized and shown afterwards.

Let's keep this bug report focused on the actual crash, please.
