Hi Joe

It crashes somewhere in the error recovering code of lxml. Chances are
either cython or lxml do something that pypy is unhappy about.

We're just discussing a medium-term plan how to fight with such issues
(it migth be a missing incref in a place where CPython doesn't care
for example), however for now fixing cython and/or lxml seems like the
only option.
