           Summary: "ksmserver could not be started" when starting KDE
           Product: kde
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED

          Priority: NOR

Backtrace

Version:           unspecified (using KDE 4.8.0) 
OS:                Linux

When logging in from kdm, KDE crashes with the error message "ksmserver could
not be started" and a message from KCrashguard.

A long thread could be found in the kde forum:
http://forum.kde.org/viewtopic.php?f=67&t=98769&p=214786#p214786

To sum up:
Seems, as something goes wrong with libqca2. When starting ksmsererver
manually, it works. When starting with startkde, KDE crashes. 
Backtrace is attached to this bug report. If the powerdevil service is
deactivated in the KDE startup settings, the keyboard service is listed in the
trace next to the libqca2 error messages (instead of the powerdevil service).
Therefore it seems that any process that uses libqca2 results in a crash.

Reproducible: Always

Steps to Reproduce:
Login to KDE from kdm

Actual Results:  
KDE crashes

Expected Results:  
Well, KDE should start, of course. :-)

- openSUSE 11.4 64bit
- KDE is installed from KDE 4.8 Core repository
(http://download.opensuse.org/repositories/KDE%3a/Release%3a/48/openSUSE_11.4/)
- all KDE packages are up to date and are installed from KDE 4.8 Core, QT too.
- installed version of libqca2: 2.0.3-18.2
- downgrading to KDE 4.7.1 from openSUSE 11.4 repo did not work
- deleting .kde4 did not work
- creating a new user and logging in: same result

Starting another desktop manager like LXDE is possible, KDE apps can be used
with limitations (e.g. not running services like nepomuk).
