happen if the G2 was imported with rewrite on, so the g2_url in the
g2_map table has a shortened url, but then rewrite is disabled and the
.htaccess mod_rewrite rules are sending over a &g2_view=core.DownloadItem
request. Fixes#1728.
Note: For a perfect solution, we should add 2 map entries for each of G2's ShowItem and DownloadItem URLs, one for short and one for long style URLs.
E.g. A G2 installation might have been using short style URLs not for its complete lifetime. And long style URLs are supposed to work in G2 even when short style URLs are enabled (and its used that way in bbcode / as a way to get permenant, id based URLs from G2).
