Tested -7 - still fails with kmail / akonadi...

This update has been unpushed.

Confirmed working in qt5-qtbase-5.9.1-9.fc27.

karma: +1

Confirmed fixed.

Seems it prolonged twice withstand of Plasma before unrecoverable crash from max 1-3h to 6h with the lack of about 2 GB unsegmented coredump that can not be reported :)

• 'unrecoverable crash' refers to missing of widgets, walpaper and panel(s) on the screen with all opened programs running & ability to switch between desktops/activities with keyboard.

** 'switching between' proceeds with all activated Compositor effects. So, by all appearances, 'unrecoverable crash' refers to all that missing because disappeared

And it generally disappears after several successful restarts.

• It was not observed in F26, in terms of it was not dissapear :))

Backtrace after 1st revival crash and about of 2 hrs from start.

This latest problem (by anonymous) is most likely unrelated to this update. If it persists, please file a bug @ bugzilla.redhat.com against qt5-qtdeclarative component.

works

@rdieter

O.K. I will try to as soon as it will be possible: abrt reports an error on this occasion at the moment:

No segments found in coredump './coredump'.

What I have been described, was observed until yesterday, when my system was not upgraded to qt5-qtbase-5.9.1-9. And after that upgrade plasma restarted once or twice during 12h or so, but not fatally.
