Package: pidgin
Version: 2.5.5-100
Severity: normal
This is bug in new libxml2-2.7.3.dfsg1 - inside libxml big mess of error
reporting callback trampolites. At least, libxml have bug [1] and need this
small patch:

} else if (channel == NULL) {

else
channel = xmlGenericError;
without this patch libxml overwrite user-defined error reporting callback
with it's own empty internal trampoline and crash.
And this patch for pidgin:

first part shutup libxml error when jabber auth success, second - add
