I also didn't ask you to attach the full strace but told you that you
should use it to find out where the process is waiting. :-) But I should
have write a warning that the strace will contain the password so some
testing password should be used.

Also attaching a gdb to the process and printing a backtrace (especially
with relevant -debuginfo) packages can help to find out where the
process is waiting.
