Reini -

The other related RT (39742) is marked resolved after 1.0; we're now at 1.7.0, and this report 
was against 0.7.0.

I'm going to mark this ticket as resolved also - if you find you're still having issues against 
1.7.0 or a trunk, please open a new trac ticket at https://trac.parrot.org/ (including a 
pointer back to this ticket if it's a related issue.)

Regards, and thanks for the report.
