When coming from sleep mode, Webkit 377 crashes and needs to restart.
Could you please attach a crash log? See <http://webkit.org/quality/crashlogs.html> for information about obtaining crash logs.
Francis, without requested crash log we are unable to proceed with this report. I have to close this report now. Feel free to reopen it, if you still experience crashes but remember to provide requested details. Please see <http://webkit.org/quality/bugwriting.html> for information about the sorts of information to include.
