Comment(by TEMHOTA):

 Now, libxml2 strictly check xml validity. So adding this patch - cure
 problem when login to jabber server, but not cure crash at all.
 There is big mess of threaded/not-threaded internal callback trampolines
 in libxml. Now, clean version overwrite error reporting callback (see:
 http://bugzilla.gnome.org/show_bug.cgi?id=564217 ), modified libxml call
 jabber callback once and still crash with same symptom.
 So - this is problem with libxml2 not with pidgin.
