Weird.  It sounds like the max message size of the Yahoo protocol has
gotten smaller (or maybe pidgin 2.5.5 adds more overhead?).

You can try this:

In your pidgin/purple directory (the same directory your
otr.private_keys file is in), make a text file called
otr.max_message_size and put this line in it:

prpl-yahoo	800

that's a tab between the protocol name and the number.

See if that works.  Try slightly smaller numbers if it doesn't.  [The
default for yahoo is 832.]

Please report back if making this number smaller fixes things.  (Or if
it doesn't, I guess.)

Thanks,
