Interesting.  With tramp-cleanup-all-connections I didn't need the two-step process to trigger the bug.
Again, the problem is that test -e suppresses the rest of the command line in /bin/sh on Solaris, so the first "test -e" fails right away, but is somehow recovered using another attempt that uses test -d. The attempt to find-file (open) .bash_history then completely fails on what seems to be the same kind of "test -e" (hmm, why didn't it do that in my previous tests before I wrote the tramp file).

resulting tramp file as well as debug buffer (slightly sanitized) attached.

Grüße, Carsten
