Summary:                    raptor registers global SAX structured error
handler, breaks other programs not expecting this
Description: 
(apologies, I'm unsure which category is appropriate for this)

libraptor sets the global libxml2 structured error handler (via
xmlSetStructuredErrorFunc) when parsing documents. Due to a bug in libxml2
[0], this global error handlers overrides any context-specific structured
error handler.

libraptor is used by liblrdf, which is in turn used by the gstreamer
ladspa plugin, which is in turn initialized because Pidgin uses gstreamer
for sound support.  Pidgin's XMPP protocol support uses a SAX parser and,
when structured errors occur, crashes because libxml2 calls libraptor's
handler [1] [2].

Ideally, your library would not be registering libxml2 global error
handers, but instead would be initializing the per-context serror
function.
