I'm getting this error when I load the page of an uploaded SVG file:

*Error creating thumbnail: Unable to create temporary thumbnail file*

In the wiki's debug log I'm also getting:

File::transform: Doing stat for mwstore://local-backend/local-thumb/7/71/WorkInProgress_DocumentIcon.svg/185px-WorkInProgress_DocumentIcon.svg.png FileBackendStore::getFileStat: File mwstore://local-backend/local-thumb/7/71/WorkInProgress_DocumentIcon.svg/185px-WorkInProgress_DocumentIcon.svg.png does not exist. SvgHandler::doTransform: called wfMkdirParents([..home..]/public_html/w/images/temp) [thumbnail] Thumbnail failed on [...server...]: could not link [..home..]/public_html/w/images/temp/svg_c36de9bd1028590fb24e2c04/WorkInProgress _DocumentIcon.svg to /[..home..]/public_html/w/images/7/71/WorkInProgress_DocumentIcon.svg

Permissions for /public_html/w/images/temp are 755 and it is owned by the correct user and group, as far as I can tell.

How can I debug this issue more? Thumbnails seem to work fine for all other formats.

Kind regards,

Manu
