Make a patch using diff -uw and submit it to the patch tracker.
Since I am not familiar with the patch tracker, below is the plain-text version. Please also see attached file if this list also accepts attachments like gem-dev does. The fix is rather simple and should be straightforward to understand.
P.S. This is a patch applied against a freshly updated CVS checkout.
Many thanks!
Best wishes,
Ico
