Quick fixes for RSS-feed problems in SnipSnap 0.5.1a 
Upgrading to SnipSnap 0.5.1a has gone smoothly with a few exceptions. One such exception is RSS feeds.
As they are, SS 0.5.1a's RSS feeds are broken in (at least) two ways. First, the HTML that SnipSnap generates advertises the associated RSS feed as being at
base/ss/exec/rss, but visiting that URL causes a 500 Internal Error because there is no
snip=snip in the associated QUERY_STRING. Second, the RSS that is generated contains relative URLs, but they are broken w.r.t. the
link elements in the RSS
item elements, which many news aggregators use as the HTML BASE when displaying encoded feed items. As a result, images don't load, and links don't work.
The fix, as usual, is to add a few Apache RewriteRules:
# The following workarounds are for SnipSnap 0.5.1a's broken RSS feedsRewriteCond %{QUERY_STRING} !snip=
RewriteRule ^/ss/exec/rss$ /ss/exec/rss?snip=start [L,R]RewriteRule ^/ss/space/theme/(.*) /ss/theme/$1 [L,R]
RewriteRule ^/ss/space/space/(.*) /ss/space/$1 [L,R]
