If none of the crash handlers catch this (like abrt or drkonqi), you can try 
running plasmashell under gdb to get a backtrace.  One way, use krunner 
(ALT-F2) to launch konsole, then run:

gdb /usr/bin/plasmashell

...

(gdb) run

... wait for crash...

(gdb) thread apply all backtrace

and post the result (ideally, you may need to install some -debuginfo to get 
a more useful backtrace).
