With PdfHandler enabled, I get a MW-Exception when uploading pdf-files to my wiki (using MW1.28). If PdfHandler is disables in LocalSettings.php everything is fine, also Thumbnails for existing Pdfs seem created normally.

Here is a log of the Exception:

Here config for PfHandler in LocalSettings.php

wfLoadExtension( 'PdfHandler' );
$wgUseImageMagick = true;
$wgPdfProcessor = 'gs';
$wgPdfInfo = 'pdfinfo';
$wgPdftoText = 'pdftotext';
$wgPdfPostProcessor = 'convert';
$wgPdfOutputExtension = "jpg";
$wgPdfHandlerDpi = "400";
$wgPdfHandlerJpegQuality = "95" ;
$wgPdfCreateThumbnailsInJobQueue = "false";

Any idea, what I am doing wrong? Thanks!

93.57.2.190 (talkcontribs)

I've the same issue...

I got the same and found phabricator:T50700

As a workaround, to avoid the exception for now set:

$wgPdfCreateThumbnailsInJobQueue = false;
