Subject: [PATCH] Fix PHP error which comes because session_start() is called
 before the obgzhandler ob_start and if session.use_trans_sid is activated.

Currently this is more a hotfix - it effectively disables gzcompression on servers with use_trans_sid. We would need to move serendipity_gzCompression before session_start, but I don't dare touch this beast I have no knowledge of. Tom?

+    * Fix error "Warning: ob_start(): output handler 'ob_gzhandler' 
+      cannot be used after 'URL-Rewriter'" which can occur on installations
+      where session.use_trans_sid is activated and Serendipity's gzip
+      compression is used. (garvinhicking)

     * Adjusted checking for "convert" binary in installation for
       Windows servers. Thanks to BobRock! (garvinhicking)
