Description Pana Sum 2016-08-06 14:59:19 CEST 
Description of problem:
Akregator crashes when closing the application if the systray icon is disabled and a feed is being shown. It does not crash if the welcome screen is shown.

According to the KDE bug reports tool, this is an upstream bug already reported and fixed in version 5.3 (Mageia 6 has 5.2.3): https://bugs.kde.org/show_bug.cgi?id=365608

Could the fix in that bug report be included in the version included in Mageia 6 ? I can test the package if you want.

Version-Release number of selected component (if applicable):
5.2.3. It is fixed upstream in version 5.3

How reproducible:
Always

Steps to Reproduce:
1. Disable systray icon
2. Open one feed
3. Close akregator
