I tried but the "paste!" (submit) button timed out, ended in 502 gateway
error. I think the pasted content (60meg?) was too much.

I posted a message to launchpad (the bug report Walter linked to) and
attached it there. (It didn't occur to me to compress it. Launchpad timed
out trying to accept that msg/attachment. Hopefully I didn't create
duplicate messages.).

HOWEVER!!! (cue the party hats and kazoos): as I was trying to navigate my
way to see previous strace file's size (via it's "properties")... PCManFM
crashed! I don't remember exactly where I was getting to where I was trying
to be. I don't think I reached the "right click").

I will post another msg there with that strace file.

After I posted that last update, I was thinking how GIMP hasn't crashed 
since I started stracing pcmanfm. It would previously crash *a lot*. 
Much more frequently than the typical *days* between pcmanfm crashes. 
That seemed to confirm my suggestive mind that strace is throttling 
things and preventing a timing problem.


However, I haven't use GIMP as much lately. So, I just took a picture 
(I'm fostering a dog and was overdue for a new photo).


The first thing I noticed using GIMP (2.10.8): the strace log was going 
absolutely wild. I'm stracing pcmanfm. Usually it stops emitting when I 
switch to an application. (I haven't tried a lot of apps. But, I thought 
I saw that when switching to my chrome browser. The log went dormant.). 
But, with GIMP, constant log activity (but I'm not stracing it).


So, that confirmed to me stracing is slowing GIMP down and it wasn't 
hitting the "timing problem" I've been imaging about all this (clicking 
too fast, or something).


Alas... GIMP finally did crash. It didn't freeze (which it used to do). 
It just disappeared. It's been disappearing. I haven't paid attention to 
whether freezing stopped, or when freezing and disappearing have both 
been occurring. (Come to think of it, I think pcmanfm has disappeared 
too -- in addition to, or replacing the freezing behavior. I stopped 
paying attention and it was all the same thing to me.).
So, I have strace-pcmanfm output when GIMP crashed. Maybe someone would 
like to ponder that? I tailed the last 500k (60mb) lines to a new file. 
That's 21 seconds worth before I ctrl-breaked out of strace (which I did 
within 3-5 seconds of GIMP crashing). Remember, the console (stderr) was 
being captured too. (I don't think I could differentiate that output if 
I saw it in there.).


If there's a place I could upload that, let me know. (I can post it to 
the bug report. I was thinking this is kind of different and related 
more to my speculation here.).
