First of all, thank you so much for your very prompt reply!
That's really appreciated.
It's unfortunate (especially for me!) that you do not experience the
segfault that I see... :-p
I tried to figure out which exact package upgrade is the cause of the
regression on my box. In order to do so, I re-upgraded all the packages
I had upgraded (and then downgraded again...) this morning. One small
set of related packages at a time.
Now I have only 1 package left to upgrade: libglibmm-2.4-1v5
If I upgrade that package too:
# aptitude --purge-unused safe-upgrade
The following packages will be upgraded:
libglibmm-2.4-1v5
1 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I get the segfault:

I no longer get any segfault:

and jackd seems to work correctly (tested with audacious output,
I can listen to music without any issue).
Hence, it seems that the bug is in libglibmm-2.4-1v5/2.66.1-1 .
Now I wonder why you are not experiencing the same bug...

I can try to do so.
Could you please assist me?
I would like to use the new method that loads debugging symbols from
the Debuginfod server, but I have never done so before...
Should I follow [instructions] on the Debian Wiki?
