The CoreDump has been removed, setting as public.

Marking as Triaged since there is a valid looking stack trace. Lots of reports in a VERY short period of time is worrisome for major impact, so marking importance as critical for now. If it is determined to have lower impact that what I think, feel free to lower importance.

Happend to me after selecting TRY netbook remix, right after login. I am booting from USB using USB creator default in Ubuntu and I set it up to save settings on the usb. After I installed my language and rebooted the crash didn't occur. Just the first time I booted.

Since upowerd autorespawns at the next request, and this only happens if there is a policykit failure (which shouldn't happen in a regular desktop environment), this shouldn't actually break things too much. Downgrading to high.

[Martin Pitt (pitti)]

This can be reproduced by editing /usr/share/polkit-1/actions/org.freedesktop.upower.policy and damaging the suspend privilege name, e. g.

    <action id="org.freedesktop.upower.suspendx">

then the polkit call will throw an error, which leads to a segfault:

$ sudo killall upowerd
$ sudo /usr/lib/upower/upowerd -v

In another terminal, do "upower --dump", and see upowerd crash with

(upowerd:13852): GLib-WARNING **: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Remote Exception invoking org.freedesktop.PolicyKit1.Authority.CheckAuthorization() on /org/freedesktop/PolicyKit1/Authority at name org.freedesktop.PolicyKit1: org.freedesktop.PolicyKit1.Error.Failed: Action org.freedesktop.upower.suspend is not registered
Segmentation fault

Looks like this was fixed in

Fix uploaded to Debian sid, and (fake)synced into maverick, so it's in the unapproved queue now.

@release team: if this is too late for maverick final, please reject, and I'll prepare an ubuntu specific package as an SRU.

[Launchpad Janitor (janitor)]

This bug was fixed in the package upower - 0.9.5-4

---------------
upower (0.9.5-4) unstable; urgency=low

  * Add 00git_initialize_polkit_gerror.patch: Ensure we've initialized errors
    when calling into PolicyKit. Patch cherrypicked from upstream git head.
    (LP: #648414)
  * 00git_fix_double_dbus_return.patch: Unfuzz to apply on top of previous
    patch; now it exactly matches the upstream commit.
