If people are still able to reproduce this we should definitely fix
it, but it only needs to be treated as a security vulnerability if a
remote user is able to cause Pidgin to hang by sending you that
string.  For what it's worth I wasn't able to reproduce this using
Pidgin 2.8.0 on 32bit Windows XP.  Hopefully someone here is either
familiar with this bug or has access to 64bit Windows 7 and can test.
