Mail: BadArgumentsError in Gmail backend

When I try to log in in any type of e-mail through the AWN mail applet, nothing happens after I click login, no matter how long I wait. Furthermore, these errors show up in the console:

When I try to do gmail:

Traceback (most recent call last):
  File "/usr/share/avant-window-navigator/applets/mail/mail.py", line 491, in onsubmit
    t["callback"](t["widgets"], self.__parent.awn))
  File "/usr/share/avant-window-navigator/applets/mail/mail.py", line 127, in perform_login
    self.mail.update() # Update
  File "/usr/share/avant-window-navigator/applets/mail/mail.py", line 522, in update
    if not self.key.attrs.has_key("username"):
  File "/usr/lib/pymodules/python2.6/awn/extras/awnlib.py", line 995, in __getAttrs
    return gnomekeyring.item_get_attributes_sync(None, self.token)
gnomekeyring.BadArgumentsError

When I try to do POP:

Traceback (most recent call last):
  File "/usr/share/avant-window-navigator/applets/mail/mail.py", line 491, in onsubmit
    t["callback"](t["widgets"], self.__parent.awn))
  File "/usr/share/avant-window-navigator/applets/mail/mail.py", line 122, in perform_login
    self.mail = self.back(key) # Login
  File "/usr/share/avant-window-navigator/applets/mail/mail.py", line 721, in __init__
    if key.attrs["usessl"]:
  File "/usr/lib/pymodules/python2.6/awn/extras/awnlib.py", line 995, in __getAttrs
    return gnomekeyring.item_get_attributes_sync(None, self.token)
gnomekeyring.BadArgumentsError

Interestingly, if I try POP *before* gmail, it seems to just freeze. No error, nothing, but the mail applet freezes and can't be accessed anymore.

I am using Ubuntu 10.04 LTS
