Bug ID: 391263
Summary: [Activity Pager - wayland] - creates a crash on Exit
Product: plasmashell
Version: 5.12.2
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Pager
Assignee: h...@kde.org
Reporter: mvourla...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
The following crash was discovered from Latte under wayland. Latte was crashing
on exit because of the Activity Pager. Activity Pager is using a
Wayland::PlasmaWindowManagement faulty!
Latte has the same issue, it is parenting the PlasmaWindowManagement at an
object that isnt deleted when closing the application, as such KWayland does
not get a signal to delete that PlasmaWindowManagement. This isnt happening
with libtaskmanager and I must rework the Latte Wayland WindowManagement (I
wasnt resposible for that code in Latte v0.7)
the ActivityPager backtrace is the following:
Application: Latte Dock (latte-dock), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
