Please see my earlier post in this thread regarding how to get a

This is a great debugging harness; thanks for pointing it out as I 
didn't know about it.

I am currently reporting my pan-crashing-Wayland crashing issue on 
gnome.org---but in the true Heisenbug fashion it stopped crashing,
so
I 
can't reproduce it now. It was crashing almost every time I used
the
pan 
newsreader (the three crash dumps I submitted were just few days
apart 
in my coredumpctl records), but now they're as solid as rock.

I have to say that the GNOME developers responded almost
immediately, 
and I feel stupid for not being able to demonstrate replication. I
am 
really curious about the nature of this bug: it must be some weird 
interaction---perhaps related to memory use or something like that.

I had the same experience.  I loaded all the tools that were
recommended, and the crashes seem to have stopped ( that is no
crashes
since I loaded all the tools.) Maybe there is a hidden fix in the
debug
stuff.

spoke too soon.  Just got logged out.  Had just finished looking up
some info on bitcoin on the web, then closed the browser, moved the
mouse toward the top annunciation in the top banner of the desktop. 
Screen went dark and dropped me out to the login window.

Checking logs and backtrace to see if I can find anything useful...
Later post if I do.

This doesn't tell me anything, but I'll bet some of you systems guys can see through it to see the root cause, or at least a good trail to follow.
