Our SVG renderer librsvg seems essentially unmaintained.
The only commits for more than a year now were mainly build fixes and some minor code optimizations as you can see from GIT log . No render bugs were fixed since a very long time. A decent amount of patches accumulated in the GNOME bugtracker , but nobody seem to be committing them. I tried to contact the developers by mail to ask if they could commit some patches but didn't receive an answer (see , which is a thread on GNOMES development mailing list I posted regarding the issue but didn't produce any really useful input either).
Since we have a huge amount of librsvg bugs downstream  - some of them quite nasty - and none of them has the slightest chance of getting solved without librsvg development continuing - I hereby ask to find a solution for this problem. Since this actually blocks many bugs, I also adjusted the priority accordingly since I think this problem needs to be addressed as quickly as possible. I could think of three options right now (but maybe someone else has other ideas):
- Get bug 38010 fixed (Re-evaluate librsvg as SVG renderer on Wikimedia wikis)
- Recruit a WMF employee or a volunteer with commit rights to GNOME Git who maintains librsvg for us
- Establish contact to the current maintainers (and hope they'll have some spare time to donate for the good of Wikipedia).
