Example project that crashes umbrello when opening.

Operating System: Linux 3.13.0-32-generic x86_64
Distribution: Ubuntu 14.04 LTS

Hey everyone,

I encountered the problem in one of my own files when I created an alternative
combined fragment in one of the sequence diagrams, but I was able to reproduce
it multiple times.
I attached a minimal .xmi-file that causes umbrello to crash immediately on my
system when I try to open it.

All KDE packages I use are from Ubuntu's standard repositories.

Please let me know if you need additional information.

Best wishes,
Philipp Harms
