Comment (by madair):

 I'm pretty sure this is a MGOS bug with tiled maps.  The equivalent
 function with untiled maps works fine.

 Tracing the error into the source file (line 1041 of
 ServerRenderingService.cpp) reveals that MGOS is making a call to
 map->GetViewCenter() which seems to be failing probably because the map
 extents have not been set.

 To test this theory, I did a QUERYMAPFEATURES call first (which failed as
 above), then I made a call to GETVISIBLEMAPEXTENTS using the web tier test
 page, and then re-issued the same QUERYMAPFEATURES request and it worked
 properly.

 I will file a bug in the MGOS trac system.
