Thanks for your report.
As already discussed in irc, ft fixed the bug in HEAD.

Hi,

grml debs=*.deb doesn't work at the moment. zsh doesn't tokenize variables by
default any more, so dpkg complains that it cannot find multiple files.

At least while testing, setopt shwordsplit helps here, maybe it would be a good
idea to set this in grml-autoconfig.functions as we rely in different places on
the old behavior.

Greetings
Marc
