segfault with plasma-desktop in libplasma.so.3.0.0

Hi all,

I am running RHEL 6.5 with KDE and am finding that the desktop is crashing every so often with a problem be reported in kdebase-workspace. The actual problem is a segfault as shown in the /var/log/messages output below. It has happened twice this morning already and you can see from the log that nothing is being reported in the log immediately before it happens...

The first time it happened today I could recover the desktop by running "plasma-desktop". The 2nd time I got the errors shown at the end regarding glibc.

Here is the md5sum of my file. Can someone with a fully updated RHEL 6.5 x86-64 installation please post their to compare?

md5sum /usr/lib64/libplasma.so.3.0.0
b1a0029e248ed3394a628a9fd8d486e0 /usr/lib64/libplasma.so.3.0.0

Any ideas what is wrong here and what I can do?

Many thanks!
Ken
