Failure is in subprocess, su is just messenger here. Use "strace -f ..." to continue tracing child as well.

maybe there is some message in syslog. Try journalctl --follow in a terminal, then do "su - mary". See what messages if any appear on the log. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

:set list

Sounds like su wants to execute '/bin/bash '. ... ah, reading on in this thread I see you found it, so this is just a hint for you how you could've seen it earlier.
