Similar experience with Kubuntu daily live CD i386 20090125

first attempt to start Kubuntu led to pulsating graphics when kdm log-in expected
after rebooting to recovery console and running xfix, system booted but nepomukservicestub crashed

Bruce, you need to open a new bug report for your problem. If you can get apport to catch the crash, it can auto-generate a report like this one. Otherwise you can try to manually get a backtrace using the directions
here - https://wiki.ubuntu.com/DebuggingProgramCrash
and here - https://wiki.ubuntu.com/Backtrace

Thank you.
