When starting up the Boinc Manager application (boinc-manager) it fails to
utilise the credentials in gui_rpc_auth.cfg to automatically connect to the
Boinc client running on localhost.

Weirdly, the automatic connection to localhost does work if the Boinc Manager
is started automatically by KDEs session restore. This works even when the
client was not connected to localhost when the previous KDE session was ended.
Using boinccmd on the command line also works flawlessly.

My initial assumption was that this was somehow related to the desktop file of
the Boinc manager. However, explicitly launching boinc-manager from the command
line and thus bystepping the desktop file shows the same issue.

The behaviour I'd expect would be for the client to behave identical when being
launched via the application launcher and via KDE's session restore mechanism,
ideally auto-connecting successfully in both cases.
