Comment(by darkrain42):

 The namespace in that debug log *is* in fact an empty string (it _should_
 never happen).

 Slightly edited to fit in a normal-ish sized window:
 {{{
         <c node=\"http://home.gna.org/xmpp4r/#0.3.2\" hash=\"...\"
 ver=\"...\" xmlns=\""/>
 }}}

 I'm attaching a patch -- even if this should never happen, it shouldn't
 crash Pidgin.
