I would not go so far as to say that I /make/ my machine crash
frequently. I intentionally created one crash - when Paul requested a
backtrace using gdb.

There are/were two different crashes. One type was when the theme was
changed while Claws was also running. Let's call this the GTK-crash. I
eventually learned what was causing them and a subsequent update of a
package eliminated that crash when LXDE is used. The intentional crash
above, falls into the this category.

The other crashes, we'll call the 'X11-inspired crashes', occurred out
of the blue, I would minimize Claws to web browse, then maximize it to
send, read, or reply to an e-mail. I unexpectedly found Claws
unresponsive/frozen each time, then it eventually crashes. It would take
anywhere from one to 15 minutes of being unresponsive until the crash
actually occurs. The poll frequency was every 12 minutes and in one
instance while the Claws interface was frozen, it still polled the
accounts.

As for Fedora Bugzilla, the bug report for this issue (X11
poll_for_event, # 1758384) was opened 4 October 2019 and currently
references 97 duplicate bug reports, including mine.
