EFL WK2 layout test has been broken since ubuntu 13.10. Especially below test modules come to crash. - batterystatus - compositing - fast/canvas/webgl - fast/events/touch - http/tests - webgl
It looks Bug 131675 can solve this issue as well.
Battery status tests don't come to crash since ubuntu version was bumped. Unskip batter status on r173863. http://trac.webkit.org/changeset/173863
Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
