[OTR-users] Long Yahoo! IMs cause problem w/ Gaim/OTR?

[Mark G. Spencer]

Hi Ian,

Do you know what the IM character limit for OTR is?  Or is the problem
actually with the Gaim plugin not OTR itself?  I'm wondering if we use
Adium X instead if we can avoid the infinite loop of errors that
happens when an IM that is too long is sent.  Lately it has been
happening a lot where my coworkers will copy and paste something into
their Gaim (OTR and Yahoo!) and we end up having to close Gaim on both
sides of the conversation.
