I have a case where the generated PDF has an empty map:

This is what I see in the QGIS Server logs:

The map object in the composer is named "MAP 0", while the log trace above includes references to "MAP%25S", which is "MAP S".

And the GetProjectSettings response has this:

  <ComposerTemplates>
   <ComposerTemplate width="297" name="Carte" height="210">
    <ComposerMap width="230.418" name="map%s" height="184.263"/>
   </ComposerTemplate>
  </ComposerTemplates>

Suggesting that QGIS Server changes the map object from "map 0" to "map%s" in the GetProjectSettings.
