Recent Mac nightly builds fail to launch
I am not sure exactly when the problem was introduced but neither MuseScoreNightly-2013-03-14-2054-452cdc7 nor MuseScoreNightly-2013-03-14-1639-91a0464 will launch on my system.
Builds from the beginning of the month do launch without error but I haven't tested the builds in between.
I decided to work backwards to see which was the last build which will launch and it seems the 2 builds I mentioned are the only ones that don't. MuseScoreNightly-2013-03-06-0953-d4749e2 opens without problem.
