Comment 1 Christoph Feck 2013-09-09 21:42:32 UTC

From looking at the backtrace, you also visited the Telepathy (Instant Messaging) settings module in System Settings. If this is reproducible, please check if not visiting that module avoids the crash.

Comment 2 Albert Astals Cid 2015-09-26 10:55:43 UTC

I can't reproduce this using a modern Plasma 5 system.

I know this bug is old but do you remember if you could reproduce it every time or was a one off crash? 

Can you still reproduce it?

Comment 3 John Schneiderman 2015-09-28 15:49:38 UTC

I am no longer able to reproduce this error.
