Certain Google Drive documents crash with webkitgtk-2.2.x (Fedora 20 / GNOME 3.10), while they did not with webkitgtk-2.0.x (Fedora 19 / GNOME 3.8). See the GNOME and WebKit bugs for more details on how to reproduce. I have webkitgtk3-2.2.2-1.fc20
webkitgtk3-2.2.2-2.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/webkitgtk3-2.2.2-2.fc20
Proposing as a freeze exception issue (suggested by rishi): this is a function you might reasonably use on a live image, so it'd be nice to fix it.
Discussed at 2013-12-02 freeze exception review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2013-12-02/f20-blocker-review-%234.2013-12-02-17.02.log.txt . Accepted as a freeze exception issue per justification in description, fix looks to be well tested.
webkitgtk3-2.2.2-2.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report.
