Couldn't get a better stack trace from users so far :/

I wonder what .policy file causes this? Can you try running polkit-policy-file-validate /usr/share/PolicyKit/policy/*.policy' and, ideally, single in on the buggy file? And attach it here? Then it's easier to fix.

(And ideally, inform the owner of the package shipping that file that they need to run p-p-f-v in 'make check')

Either way we shouldn't crash...

I don't experience the crash myself, but I'll forward your comment.

This bug report is for the old version of PolicyKit. Closing as all of the code has been rewritten. Please reopen if the bug report applies to the latest version of PolicyKit. Thanks.
