While trying to diagnose an issue with a specific SVG image rendering oddly at small sizes, I noticed that trying to create a previously nonexistent thumbnail of an SVG image via thumb.php occasionally fails with the following error:
Error creating thumbnail: /usr/local/apache/common/php-1.5/bin/ulimit4.sh: line 4: /usr/local/bin/rsvg: No such file or directory
The creation usually succeeds after a couple of reloads; I suspect the problem may happen only on some hosts. (Note: To recreate the problem using the URL provided, you need to purge the thumbnail cache for the image in question first.)
Version: unspecified
