[Message part 1 (text/plain, inline)]

Happened again. See attached `BACKTRACE' and `TRAMP-LOG' generated after
evalling `(setf tramp-verbose 10)'.

Note this suspicious entry in the log:
10:26:36.864700 tramp-get-remote-tmpdir (1) # File error: Directory
/ssh:USER <at> HOST#22222:/ssh:USER <at> HOST#22222:/tmp not accessible

Mentioned Git commit cannot be found, because I build Emacs with a few
minor local changes. I can assure you they have nothing to do with TRAMP.
The build is from 14th of September, so upstream commit number should be
around 997284d2a5 or so.

I will keep this Emacs instance around in case you have questions.
