Thanks for the report, Glen.  From the silence, I think we're all a bit
puzzled.

I don't know how to reproduce it; my build of 12.04 starts up normally and
I assume the rest of the dev team hasn't encountered anything so drastic
either.

I did a little digging, though.

At first I thought the problem related to this warning "track id not
found, this is probably a BUG".  But now I think that's a red herring.  I
don't think it's that Composition is failing to make tracks.  getTrackById
is called from many places, sometimes quite early, and in some of those
places it's clearly expected to miss, for instance AddTracksCommand.cpp. 
Also, I see the same warning in old traces that I keep around for
reference, which had no problem starting up.

The other notable warning "AlsaDriver::renameDevice: Cannot find device 1
in port map" also occurs repeatedly in old traces.  "Cannot connect
(null)::destroyed() to > Rosegarden::AudioRouteMenu::slotInstrumentGone()"
too appears in old traces.

So up until "gthread-posix.c", I don't see anything abnormal.  We don't
even use gthread-posix directly; we use Qt threads, which I assume call
it.

So I'm quite puzzled.
