Comment(by djflux):

 There seems to be some issue with bad-data trapping in
 sipe_add_lcs_contacts and/or purple_utf8_strcasecmp.  I think I have some
 corrupt entries in my LCS server-based contact list and when Pidgin tries
 to setup my contact list it gets non-standard (read non UTF8) characters
 in the list it gets back from the server.

 I can probably remove the corrupt Group from my contact list, but I wanted
 to leave it around so that we might be able to trap the problem so that it
 doesn't cause pidgin to core dump/backtrace.

 Here's some debug output:

 I'll take a look and see if I can trap for the bad characters before we
 try to add the contact/group.
