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
