Pidgin will not allow me to send messages any more than 5 or 6 words long

Binary package hint: pidgin

Every time I send an instant message with Pidgin that is anywhere over about 6 words in length, I get an error message in my IM window that says that the message could not be sent because it is too large. How can I correct this problem? All other IM clients I have used do not have this issue.
