When using embed form of MultimediaViewer, there is currently output like this: [[File:Image_path_with_spaces.png|thumb|Image path with spaces]]. "File:Image_path_with_spaces.png" should be "File:Image path with spaces.png" since the underscores are not needed to provide a correct image usage.
Change 153791 had a related patch set uploaded by Thiemo Mättig (WMDE): Use spaces in Embed as Wikitext code https://gerrit.wikimedia.org/r/153791
