           Summary: Plasma crashed by Lancelot or ggl plugins after
                    openSUSE update
           Product: plasma
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: plasma-bugs@kde.org
        ReportedBy: olaf@amen-online.de


Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.4-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
I updated openSUSE 11.3 to the latest KDE 4.5 packages from the BuildService
repository
http://download.opensuse.org/repositories/KDE%3a/Distro%3a/Factory/openSUSE_11.3/

After the next system start, plasma-desktop crashes during restart. Manually
restarting plasma-desktop has the same result.

I then had a look at the backtrace and saw that the crash happens when Plasma
is trying to load the lancelot plugin. After removing all lancelot and ggl
applets from ~/.kde4/share/config/plasma-desktop-appletrc, Plasma is able to
start-up again without crash. Re-adding the Lancelot applet via the GUI crashes
Plasma again.

I will attach the original plasma-desktop-appletrc as
plasma-desktop-appletrc-original. (This crashes plasma-desktop.)
I will also attach my edited plasma-desktop-appletrc as
plasma-desktop-appletrc-changed. (This doesn't crash plasma-desktop.)
And I will attach a diff between the two versions of the file as
plasma-desktop-appletrc-diff.

The crash can be reproduced every time.
