When migrating from 0.5.x to 0.6, the format of stored
queries changes. Our first approach was to dump the
queries using roundup-admin, change the text in an
editor and change the "url" text. Urls contain lots of
'=' characters. Roundup-admin will complain with a
syntax error, because it does not accept the '=' in the
command. Example:
roundup-admin -i /tttech/org/software/roundup/tttech
set query2 url='columns=id,
category,title,status,deadline,part_of&:sort=-id&:group=kind&:filter=status,kind
,responsible&status=1,2,3,4&kind=1,2,4,3&responsible=63&:pagesize=30&:startwith=
0'
will barf. I'm not quite sure if we have retried with
0.6.2 but for 0.5.6 it does not accept the changed url.

In what way does it barf exactly? It works for me on HEAD.

Works for me on 0.6.2, seems to have been fixed after 0.5.
