 After upgrading to pidgin-2.4.3-no-gtk.exe on a Windows NT system that had
 been running fine with pidgin-2.4.2-no-gtk.exe, Pidgin now always crashes

 Reverting to 2.4.2 restored normal behavior.

Comment:

 Hmm... that's odd.  The code where it is crashing hasn't changed at all.
 The only thing I can think of (which '''shouldn't''' be an issue) is that
 the 2.4.3 win32 build was cross-compiled on a linux system, and we usually
 build stuff natively on a windows system.
