Bug ID: 369406
Summary: Plasma desktop shell crashes after login
Product: plasma4
Version: unspecified
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: m.j.ever...@iee.org
Logged into KDE, plasma attempts to load, then crashes (segfault. #11). Plasma
then retries to load, crashes again (as before), and DrKonqi appears with the
crash information. Insufficient information in backtrace to take a guess on
what's causing it, presently!
Reproducible: Always
Steps to Reproduce:
1. Boot
2. Log into KDE
3. Observe Plasma attempt to load, then segfault and crash.
Actual Results:
Plasma segfaults and exits
Expected Results:
Plasma loads, deskop appears, systray/panel etc. appear on screen (as you might
expect!).
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
