I believe I just experienced this same bug with up to date packages.
It happened when I went to open "User Accounts".
I've marked this as new.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Sebastien Bacher (seb128)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

[Sebastien Bacher (seb128)]

could be bug #841280

[dysonsphere (dysonsphere23)]

happened to me as well when trying to access user account settings

ubuntu 11.10
updated this morning (oct 06) just before the crash.

[Michael DePaulo (mikedep333)]

I've attached the gdb backtrace.

I'm not sure if I'm supposed to reopen this bug or not.

I noticed this:
um_password_dialog_new () at um-password-dialog.c:690
690 um-password-dialog.c: No such file or directory.
        in um-password-dialog.c

[Sebastien Bacher (seb128)]

thanks michael, your stacktrace might be a different bug, could you send it using ubuntu-bug on the apport generated file?

[Michael DePaulo (mikedep333)]

I'll do that when I get home at around 23:00 UTC; thanks Sebastian!

[Michael DePaulo (mikedep333)]

I had to figure out how to use ubuntu-bug on the .crash file (because it wasn't prompting to file a bug when it crashes anymore), but I believe I followed your instructions to create bug 870435 .

[Sebastien Bacher (seb128)]

closing that bug since a new one got reported using apport
