This method of reporting bugs was deprecated years and years ago, please
use our bugs database, http://bugs.squeak.org/ , for 'official' reports.
That being said it's not a bad idea to ask for sanity checks on the
mailing list first and I will consider this email to be that.

Whisker has not been updated for quite a while, it's not too surprising
that you have found a problem with it.  The version linked to in the
3.10 package universe dates back to March, 2004.  There is a slighly
newer version at http://www.squeaksource.com/Services/ but I would be
surprised if it works much better.  These were both developed with and
for Squeak 3.7.

My understanding of the Package Universe was that it was meant to only
include packages known to work.  However I'm not sure of the exact
policy, it may be that inclusion is assumed until lack of support is
positively known.  How to report a problem, I don't know.
