Status changed to 'Confirmed' because the bug affects multiple users.

[Aelfwyne (aelfwyne)]

Seems to have been caused because I cancelled the keyring popup earlier in the session because I wasn't sure what was requesting it (I hadn't opened any apps that should have requested it). Later when I tried to open gtkvncviewer, it failed with this error. A reboot _might_ help but I can't reboot this machine at this time... :/

[cerr (ron-eggler)]

I get the same error but can not reboot the machine either, how did you fix it @Aelfwyne ?
