Running MuseScore (trunk revision 3679) in converter mode crashes.
E.g. "./build/mscore/mscore mscore/test/noteheads.mscz -o ~/out.mscz" results in "Segmentation fault"
Running the GUI, opening mscore/test/noteheads.mscz and saving as out.mscz does not result in a crash.

Werner,
could you have a look at this, please ? I couldn't find the cause and this issue prevents me from easily fixing the existing MusicXML import/export issues.
Leon.
These are some debug data which may help in diagnosing the bug. I tried to investigate, but the issue is too deep in mscore internals for my knowledge.
My setup: Rev. 3708 under Windows XP w/ SP3, Qt SDK 2010.04 (Qt Creator 2.0.0, Qt lib 4.7.0)
The CALL STACK at the moment of the SEGFAULT (mem addrs are probably meaningless out of their context, but I kept them anyway):
The issue pops up while attempting to set up the score 'view'. This seems to be necessary in order to properly layout the score for output but, as there is no GUI, some caution is probably required.
For the sake of completeness, this is the full backtrace generated by Qt Creator:

Hoping it may help,
