Bug ID: 370883
Summary: Crash on session restore
Product: korgac
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: korganizer-de...@kde.org
Reporter: jgh...@gmail.com
The crash occurs during login. If I disable session management or add korgac to
excluded applications, the crash does not occur. Otherwise, it happens during
every login.
Reproducible: Always
Steps to Reproduce:
1. Enable session management (SystemSettings->Startup and Shutdown->Desktop
Session->On Login->Restore previous session)
2. Make sure that korgac is not in the list of excluded apps
3. Logout->Login
Actual Results:
korgac throws a segmentation violation (SEGV) and dumps core.
Expected Results:
No crash
korgac v16.08.2
-- Backtrace:
Application: korgac (korgac), signal: Segmentation fault

This can be worked around by adding korgac to the list of "Applications to be
excluded from sessions" via SystemSettings->Startup and Shutdown->Desktop
Session->On Login.
