Description of problem:

kde3 programs crash immediately when started. I've tried this with k3b, kmymoney, kpowersave and ksynaptcs, it's always the same. when started from command line, the error is:

$ k3b
kded: ERROR: KUniqueApplication: Registering failed!
kded: ERROR: Communication problem with kded, it probably crashed.
DCOP aborting call from 'anonymous-5664' to 'k3b'
KCrash: Application 'k3b' crashing...

Version-Release number of selected component (if applicable):

Fedora 10 with all updates as of today.

How reproducible:


Steps to Reproduce:
1. Start any kde3 programme
Actual results:

Expected results:
no crash

Additional info:

I've tried uninstalling all kde packages and reinstalling but it didn't help. A search for the error message didn't get me to anything useful. I've no idea what other information is need to solve this, so please tell me what I should try.

rpm -q kdelibs3
rpm -V kdelibs3

Otherwise, logout, try:
rm -rf /tmp/kde-<username>
rm -rf /var/tmp/kdecache-<username>

Hi Rex, thanks for your suggestions.

$ rpm -q kdelibs3

$ rpm -V kdelibs3
doesn't return anything. 

I logged out into text console, removed the two tmp directories, rebooted, but the programs still crash with the same error.

Hi again, I found the problem.

Your suggestion gave me the idea to check all installed packages for integrity. It turned out that qt3 had a problem:

$ rpm -V qt3
..5.....    /usr/lib64/qt-3.3/lib/libqt-mt.so.3.3.8

So I reinstalled qt3 and it works now.
