[system-tools] Debuging g-s-t

How can I get useful debugging information?  I am running
system-tools-backends 1.9.3 and gnome-system-tools 2.15.2 on Foresight
Linux.  I have patched it as a supported platform.  The network tool
seems to work fine, however the users-admin tool doesn't work.  I can
add a user and it gets displayed in the interface.  However, the account
isn't actually created.  

How can I get useful debugging information to find out where the problem
is?

Thanks,
