Looks like the crash is in the GLSL compiler code.

llvm-svn+mesa-git LIBGL_ALWAYS_SOFTWARE=1 plasmashell crash too.
Comment 6 Ian Romanick 2015-02-11 22:45:49 UTC 
It looks like the application is doing multithreaded compiles.  Since 10.4.x, there have been some fixes in this area.  Can you retry with either 10.5 branch or master?
