Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

The only problem is the dbgsyms don't seem to be available for Hardy...

For me this bug is reproducible 100% of time and I haven't changed absolutely anything from authentication, users and group settings or whatever.
I just try to create a user for which the only information is account name and password and after clicking 'Ok' it takes a second or two then crashes. (I tried filling up all fields to no avail)
Before updating to Hardy (IOW with Gutsy) I could create users just fine. (But) During the Gutsy development the users-admin app had this exact same problem/symptoms.
Creating a user with 'adduser' still works fine.

I can confirm this on a fresh (and updated) Hardy install.

I also ran into this bug. Running users-admin from the system menu fails silently, but running it from a terminal shows the segfault.
Attached is a gdb backtrace with symbols.
Note the error messages:

process 18508: arguments to dbus_pending_call_unref() were incorrect, assertion "pending != NULL" failed in file dbus-pending-call.c line 563.
This is normally a bug in some application using the D-Bus library.

I can also create this bug--fresh install Hardy Alpha 2. Tried to create a new Admin user & this is redult:

autocrosser@linux:~$ users-admin

(users-admin:6255): Liboobs-CRITICAL **: create_dbus_struct_from_user: assertion `(login && password && homedir && shell)' failed

I was able to reproduce this with trunk I've filled the bug upstream at http://bugzilla.gnome.org/show_bug.cgi?id=505115 , thanks!.

[Pedro Villavicencio (pedro)]

Fixed upstream, thanks.
