[Desktop-packages] [Bug 1959103] Re: polkitd crashes with segfault with specific config file
I had similar issue with the following config:
[steam-network-perm]
Identity unix-user:gry
Action org.freedesktop.NetworkManager.settings.modify.system
ResultActive no
ResultInactive no
ResultAny no
This is due to some programming bug when handling config files. Attached patch
fixes the issue for me.
