Hi Stefan,

Looks like this is a know bug, and you can find the ticket here
http://redmine.ruby-lang.org/issues/show/1556

The ticket was opened on June 2nd, but the bug appeared in the repo at 
1.8.7-p83 (unreleased version), which is 5 month old. Hope it will be 
fixed in the next release.

In the mean time, you can easily fix it yourself with the simple 2 lines 
patch detailed at the end of the ticket.

Regards
Julien
