illegal slurSegment during midi playback.

Just got/found the application and installed. Moved from 0.9.4 to 0.9.5 within a 30-minute time frame.
Installed from the ppa..thingy...

I get a fatal error when playing a midi file. Once the error occures the app. tries to finish playing the song then becomes unresponsive. In system monitor it says:

mscore.real: hrtimer_nanosleep
mscore: do_wait

When I run the application in the terminal it says:
remove empty measures 2880 ticks
