Dear Maintainer,
I am reporting the issue described at Launchpad #1299138 (originally
reported by user intherye) upstream as I can reproduce it on Debian
with gnome-system-tools-3.0.0-4.
When attempting to change the password in users-admin (a.k.a. User
Settings) to a password that is "too simple" (e.g. "a12345"), the
"Change User Password" dialog will report "Password too simple"
on the first try, but will hang on the second try. The dialog can be
closed, and one can return to "User Settings" without the password
having changed.
However, when users-admin is run from OS X over "ssh -Y", it DOES NOT
hang (always reports "Password too simple"; using OS X 10.10.1,
OpenSSH_6.7p1, OpenSSL 1.0.1j 15 Oct 2014 for macports,
and XQuartz 2.7.8_beta1).
