mscore Segmentation fault on save file as

mscore 2.0 rev. 2ec2c65

openSuSe 12.2

I wanted to use the new mscore so I got the code from git. Compiled the latest rev of mscore.

On creating a new score, adding a few notes and then doing a 'save file as', mscore crashes.

There is no information to say where the segmentation fault occurs.

Problem happens every time, but not when saving existing files.
