pkcon crashes during interactive install / remove etc. #730

Open sidt4 opened 8 months ago

sidt4 commented 8 months ago

Crashes with following command:

$ pkcon install package_X

It appears we're doing autoptr cleanup of GTask object (via g_object_unref) in both the callbacks for each action ( install / remove etc )

Backtrace:

Same during pkcon update command.
