The GIMP crashes are random (while color-balancing, contrast-brightness
adjusting, etc.). It seems similar to the pcmanfm crash because it
manifests itself when I click (and realize it's frozen). I might click to
increase/decrease the brightness (in the midst of playing with those values
before applying them).

I'm running strace now. In case anyone else is having crashes and wants to
do this too:
pidof pcmanfm
kill
strace -Ff -tt pcmanfm --desktop 2>&1 | tee strace-pcmanfm.log
I didn't add the "" parm to the pcmanfm command being straced. It
seemed clearer to let it remain attached to strace. I could have straced
the already running/disowned pcmanfm using its PID[1]. That might be
simpler. But, killing pcmanfm and starting it with strace might capture the
console output in a way tracing the pid wouldn't(?).
I use my laptop casually. I can manually rotate the log file. (Or, schedule
an hourly cron job to do it.).
Now, It's just a matter of time till I have some strace info. I'll post to
the bug report when I have something.
(Sidenote: For a long time these pcmanfm crashes were causing a "program
crashed, would you like to send a crash report?" dialog. I always assumed
someone was getting those (probably from lots of users) and divining
something from it. I haven't seen that dialog for awhile. I've forgotten if
I clicked something saying "never ask again." There was even a time when I
thought someone was trying to fix it because after an automatic update, it
seemed like the desktop restarted itself. Then it went back to me having to
open a terminal and start it manually.).
