On the whole, it just feels like Linux @font-face support isn't done yet. OK, looking at the backtraces, this looks like some problem in Cairo/Pango/Freetype. Changing the component for further analysis, but ready to accept explanation why firefox is to be blamed. Created attachment 350476 [details]
backtrace
OK, so I got this as well. I will work on reproducer.
Apparently this is fixed in cairo 1.8.8 After installing 'cairo-1.8.8-1.fc12.x86_64', I tried to no avail to reproduce this bug. That is great. I tried hard. Can cairo 1.8.8 get pushed out soon for F11? Until cairo is updated, anyone can easily produce a webpage that dumps Firefox for every Fedora 11 user. *** Bug 509574 has been marked as a duplicate of this bug. *** There is an unofficial scratch rebuild of F12 cairo for F11 at http://koji.fedoraproject.org/koji/taskinfo?taskID=1454453 The unofficial scratch rebuild of F12 cairo for F11 also works great for me. I couldn't get an embedded font to seg fault the browser with it. cairo-1.8.8-1.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/cairo-1.8.8-1.fc11 *** Bug 509634 has been marked as a duplicate of this bug. *** cairo-1.8.8-1.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report. Didn't fix my problem. Bug 509574 must have been a *different* bug. That's not at all unreasonable, since the symptoms were quite different. *** Bug 542016 has been marked as a duplicate of this bug. *** *** Bug 545503 has been marked as a duplicate of this bug. *** |
