Comment (by wenzeslaus):

 I tested the rendering with rasters, vectors and vector legend and it
 works including checking and unchecking. A debug output (WX_DEBUG=5,
 edited) after pressing ''Render map'' button is below showing only files
 in the session temporary directory which is in the system temporary
 directory (here /tmp).
