Public bug reported:
I configured Firefox to open magnet links in Transmission. If Transmission is
not open, clicking in the link it opens it. The problem is if I click in a
magnet link when already open, Transmission doesn't react to add this new
magnet link (or says that the link is already added).
The problem is related to AppArmor. I could see in the logs this line:
out 03 19:35:59 glados dbus-broker[9817]: apparmor="DENIED"
operation="dbus_method_call" bus="session"
path="/com/transmissionbt/transmission" interface="org.gtk.Actions"
member="DescribeAll" mask="send" name="com.transmissionbt.transmission"
label="transmission-gtk" peer_label="transmission-gtk"
out 03 19:35:59 glados dbus-broker[9817]: apparmor="DENIED"
operation="dbus_method_call" bus="session"
path="/com/transmissionbt/transmission" interface="org.gtk.Actions"
member="DescribeAll" mask="receive" name=":1.3038" label="transmission-gtk"
peer_label="transmission-gtk"
If I disable AppArmor for Transmission (like aa-disable transmission),
it works.
