Also, fast/dom/Geolocation/callback-to-remote-context2.html, which was introduced by r60669, http://trac.webkit.org/changeset/60669, doesn't work on GTK port.
Added it to the GTK skipped list in r60672, http://trac.webkit.org/changeset/60672
r60840 http://trac.webkit.org/changeset/60840 added fast/dom/Geolocation/callback-to-deleted-context.html which also doesn't work on GTK
Both tests are now passing and therefor unskipped because of the work made in bug #64970, landed as revision r97746. I believe this bug should be closed.
