Umm… of course it is, sorry, just a typo there.

The problem is probably in a broken version of libcroco (used by librsvg): In https://git.gnome.org/browse/libcroco/commit/?id=0cbb0dfed7350ed48a12d56925cdd76255891aa5 (on 2012-03-18), the bug was introduced per mistaken https://bugzilla.gnome.org/show_bug.cgi?id=672332

This change was reverted in https://git.gnome.org/browse/libcroco/commit/?id=b37d79049a0f9149df98e5adb4f69db69deef056 (on 2012-10-07), after which the behavior should be correct again.

Which means libcroco versions 0.6.5 and 0.6.6 are broken, and at least v0.6.7 is required to fix this (v0.6.8 seems to be current).

Not sure what is needed / who can do such an update (“ops” maybe)?

Thanks for investigating and tracking this down!

Nearly all servers run Ubuntu 12.04 Precise which ships

libcroco3 0.6.5-1

So the very best way would be convincing Ubuntu (in https://launchpad.net/ubuntu/ ) to ship a newer version of libcroco, or to specifically backport that patch. If that's a no-go, an updated package could be created based on 0.6.5-1 which includes the aforementioned, isolated patch.

The patch for Ubuntu LTS is currently in -proposed; if somebody would be able to test the package somewhere on beta/labs/whatever, that would be great.

See https://bugs.launchpad.net/ubuntu/+source/libcroco/+bug/1163999

The fix to Ubuntu LTS was released, and probably applied to WMF servers, as the image on Commons renders correctly, now.

Marking RESOLVED FIXED.
