             Bug #: 37632
           Summary: Thumbnail generation broken on 1.19
           Product: MediaWiki extensions
           Version: REL1_19 branch
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Unprioritized
         Component: PdfHandler
        AssignedTo: [email protected]
        ReportedBy: [email protected]
    Classification: Unclassified
   Mobile Platform: ---


Hi,
I've skipped 1.18 - so I'm not sure if it was working or not with this release.
On MW 1.19 PdfHandler does not generates thumbnail with generic error code 1
("GPL Ghostscript 9.05: Unrecoverable error, exit code 1").

It seems like GS does not get proper file name to convert, since it's URL file
format. For example:
mwstore://local-backend/local-public/9/9f/FreeLoaderManual-ocr.pdf

Changing this code fixes problem (I haven't seen in MW 1.19 any information
about changes in file api)
