What is this? Can't the KDE devs find the cause of a single SIGSEGV? Isn't
anyone using debugging tools? Each and every error report is pointing out
polkitqt1-agent-session.cpp, gobject.c and libgobject-2.0.so.0, along with the
entire backtraces. The problem occurs so frequently too. Just invoke the
authentication dialog more than once, for example, install a package but DON'T
cause it to remember the password (even for the session), then install another
package, again not causing it remember the password, or make modifications to
the login screen settings through systemsettings and don't make it remember the
password. Once the auth dialog has been used more than once and each time the
option to remember the password has been turned off, finally turn off (not
restart or logout) the computer. This should cause the crash. If not, perform
the whole procedure a few times. It will surely crop up. Just run it through a
debugging session and you should have the culprit.

This is an unnecessary and childish comment.

1) The problem is the bug status is UNCONFIRMED after 7 months, after 50
reports and backtraces. This bug should have been marked as CONFIRMED months
ago, and some action taken to triage and debug it.

2) The only actions you've taken so far is to mark other bug reports as
duplicates. Hardly the position where you can judge other's commitment.

3) Do you expect to be given the solution to a problem you are not even
bothered to investigate?

4) You have been given plenty of information, and a reproducible scenario. Work
with this information.

In reply to #62: Same here, the crash no longer happens. Gentoo Linux, now with
KDE 4.6.5.
