with 1.0 I get a strange error (see attached file) for
the following search url:

http://localhost/roundupTest/issues/issue?@sort=creator&@group=priority&filter=status,assignedto&@columns=id,activity,title,creator,status&status=-1,1,2,3,4,5,6

With 0.8.5 and 0.8.6 the same url works as expected. I
run a customized tracker on win XP, sqlite backend,
Apache/cgi. Until now I was not able to reproduce the
error with the demo tracker.

The error disappears if I delete the
"@sort=creator"-section.
