Ok, good so we can rule that out.

I only took a brief look but it seems the amount of information in the
back trace is not much.
Is the muse binary still built for release? Building it for debug may
give more information.

Some additional questions, sorry if you already answered before..
do you use a standard distribution? maybe we can reproduce your problem.
what settings do you start jack with?

The start of the printout below is what MusE outputs during running
with -D, right? And you are starting MusE from within gdb?

Unless you already did so I would suggest that you recompile MusE
similar to the below:
cmake .. -DCMAKE_BUILD_TYPE=debug
make clean
make
make install

Another thing you could try is to start MusE without plugins.
and use MusEs own fluidsynth (under MESS) as audio output.
muse2 -pNI2

We had for instance an issue some years ago that some plugins caused
corruption in MusE memory space due to duplicated symbol names.
