GroupMailer crash has nothing to do with the problem reported for
P2kCommander which is related to a not properly terminated GIF data.
GroupMailer crashes because its GIF contains a zero sized GIF_COMMENT
extension, and that is not properly handled. I sent a patch that should
fix GroupMailer crash as well.
