Bug 359594

Application: akregator (5.0.2)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-27-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed: Full Shutdown, or Restart. On restart, an error dialog will fequently (but not always) appear saying "standard feedlist is corrupted, a backup is created". This is useless, being a 'fresh-install' file with only the standard Kubuntu and KDE feeds - Import of a saved opml file will be required for a useful restore. My system exhibits other errors on re-start: Applications running at closedown may not re-start at startup, or if they do they are likely to not appear in their former Virtual Desktop(s). Akregator is the worst offender, but Dolphin is next worst. I suspect closedown to be too precipitous, not allowing full saving of Desktop and open window(s)  per application before shutdown/power-off. (Windows that do appear will do so at correct size and position on screen, but all are likely to appear on the Desktop active at shutdown). This behaviour began with Plasma 5.

The crash can be reproduced every time.
