Bug ID: 385703
Summary: QtWebengine documentatio viewer causes KDevelop crash
on exit
Product: kdevelop
Version: 5.1.80
Platform: Compiled Sources
OS: OS X
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Documentation viewer
Assignee: kdevelop-bugs-n...@kde.org
Reporter: rjvber...@gmail.com
Target Milestone: ---
The QtWebengine docviewer backend causes a systematic crash on exit on Mac (Qt
5.8.0).
1- launch a KDevelop session
2- click on the "Documentation" toolbar button
3- open the proposed (QtHelp) documentation section
4- repeat 2) to close the view
4- exit
After step 3) I see this on the calling terminal:
js: Not allowed to load local resource:
file:///var/folders/j1/1439ppj08xj8h6006s6drbq00000gs/T/kdevelop.N13700
(NB: that's the simple CSS the plugin tries to use)

backtrace below. The crash is deep in Qt but I haven't seen it with any other
applications that use QWE.
