I confirm the same behaviour as Jaime Fernando on comment #9: after execute
sudo killall /usr/bin/perl; sudo /usr/share/system-tools-backends-2.0/scripts/SystemToolsBackends.pl -m UsersConfig -v &> ~/stb-users.log
sudo /usr/share/system-tools-backends-2.0/scripts/SystemToolsBackends.pl -m UserConfig -v &> ~/stb-user.log
users-admin works well and really deletes the user.
