I got "Error creating thumbnail: sh: wmf2eps: command not found" when accessing an uploaded SVG image on the monitor.(cc).org site via IE7 and "convert: unable to load module `/usr/lib/ImageMagick-6.3.7/modules-Q16/coders/svg.la': file not found."
, there's same error on firefox.

, this fixed it: $wgMaxShellMemory = 131072;
great, it fixed, thanks nkinkade 🙂

but indeed, is there any relation between the error and shell memory?
