Comment 3 Tim Waugh 2011-05-24 15:05:47 UTC
Did this only happen once?

It looks like the dbus proxy was unable to find the method signature for this cups-pk-helper method.  If it only happened once I'd be inclined to suspect faulty RAM or something... a single bit-flip could cause this.

Comment 5 Marek Kašík 2011-06-01 10:01:37 UTC
Hi,

does the problem still persists? If yes, could you past here result of this command:

"gdbus introspect --system --dest org.opensuse.CupsPkHelper.Mechanism --object-path /"

Regards

Marek

Comment 7 Fedora End Of Life 2012-08-07 17:23:43 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping
