Re: [Denemo-devel] Denemo fails to start

[Richard Shann]

Ooops! I thought it was strange that I could have missed the
g_mutex_unlock() the first time, what happened was that I mistakenly
deleted the g_mutex_free() and left the unlock, and then when I looked
again saw the unlock still there and thought I'd missed it.
But this meant the g_mutex_free() was missing - this didn't crash my
machine when I tested it, but it could run you out of memory ...
Your error messages don't seem to match this mistake of mine though - 
there are now just three g_mutex_unlock()s in the C code all in
audiointerface.c and all matched with lock/trylock.
So this
Attempt to unlock mutex that was not locked
> Abgebrochen

is puzzling. On the face of it, it looks like a muddle with versions of
the program - a failed git pull, corruption of files ... I can't think
what.

Well, I have fixed the failure to free the mutex and so it is worth
testing again.
