Currently no PNG previews will be created for SVG pictures. I uploaded a.m. document and <https://wiki.documentfoundation.org/File:BugsNeedingReview.svg>. In both pages no picture will be shown, but message "Fehler beim Erstellen des Vorschaubildes: /var/www/sites/wiki.documentfoundation.org//bin/ulimit4.sh: line 4: convert: command not found".
Thanks for the hint! Installed ImageMagick, tried to set wgMaxShellMemory, but then the script grabs all available memory. Can you ping Manuel Schneider <manuel.schneider@wikimedia.ch>, our wiki expert, directly?
We need some results here, what's the problem?
convert is not able to convert the svg - it just needs too much memory. So there must be something special about this and a few other files. Looking at them, they have a ridiculously large canvas size. 28000x14000 pixel for example (the LO-qa with the meter-icon). A png of the size of 8meters x 4meters.. No wonder why convert cannot deal with it. The one mentioned in the initial comment has a canvas/document size of 29700,00 x 21000,00 pixel - those values ars suspicious, as 297mm x 210mm would be the size of A4 paper. The BugsNeedingReview.svg is ~ 8m x 6m instead of the intended ~30cm x 21cm. So this one is "wontfix". You will need to recreate the svg with a more suitable canvas size.

I did not fine anything concerning unit for those dimensions.
