Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic i686
Distribution: Ubuntu 15.04

-- Information about the crash:
When I log into my fresh installation of Kubuntu, Plasma crashes, producing this backtrace. Please note that this is a fresh backtrace, it's not a duplicate of #332422, which was closed because it's "outdated".

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
