You sound like you're using TileCache with metaTiling. TileCache sets
this property internally when using metaTiling. 

I'm surprised you're seeing this though. The code says:

            try:
                # if the metadata is already set, don't override.
                wms.getMetaData("labelcache_map_edge_buffer")
            except mapscript._mapscript.MapServerError:

Perhaps turning debug off as suggested will get rid of this...

I don't know. But this is definitely directly related to TileCache.
