Spotted in production a number of times:
No such file or directory in /srv/mediawiki/php-1.25wmf16/includes/resourceloader/ResourceLoaderImage.php on line 348
This happens when we fail to convert the SVG to PNG. The actual error happens when attempting to access the non-existing temp PNG from the conversion. The rasterize() function call should let us know, ResourceLoaderImage should handle the failure more gracefully.
