Public bug reported:

Lernid suggests that the Internet connection be reestablished, but
that's no help.

The problem is that a registered nick can be locked at the server for a
while after an attempt is made to use it without either using a
password, or when supplying an incorrect one. Telepathy does not
recognize this freenode nickserv behaviour and Lernid cannot distinguish
between this situation and a network connection problem.

The message from the server that telepathy-idle lacks from its parsing table is:
:niven.freenode.net 437 * userid :Nick/channel is temporarily unavailable

After no attempt is  to react to this for a while, this message is issued and 
the connection is closed by the server end:
ERROR :Closing Link: adsl-sb-067-061.wcnet.org (Connection timed out)

If this 437 error were reported as a nick error to the application
program, Lernid (or other application program) could try logging on with
a different nick.

The nick is again usable after the server finishes the unavailability
time and the student can then again logon using the nick as long as the
correct password is issued.

The problem only happens if the nick has "enforce" set on with nickserv,
but this is common. Unfortunately only one faulty attempt to use a
protected nick is enough to trigger this problem.

Lernid may be able to circumvent this problem, at some cost, by always
signing on to nick with a random component, and then trying to switch to
the correct nick after the connection has been completed.
