On my machine is even worst, a segfault occur :-/

Comment 3 Hugo Parente Lima 2011-10-12 00:15:04 EEST

This bug is fixed on Marcelo's branch (converters) and the fix will land on
mainline soon when this branch get merged into mainline.

The bug wasn't fixed on mainline because all the work that would be made to fix
it on mainline will be useless because Marcelo's work will overwrite it, i.e.
the bug is on converters code and Marcelo is working on a huge refactor in the
converters code.

So, by now, a unit test was created and sent to Marcelo's branch where it pass.

Regards and thanks for the report.

The converters branch was finally merged into mainline, so this bug can be
considered fixed.
