Nightly build from the 27th. Enabled sync logging to try to figure out issue with sync not working. rsoderberg was debugging and tried to visit about:sync-log. Fennec hung and then wouldn't restart.
Note that Daniel's about:sync-log was a 2.7MB file at the time, as we were trying to debug why his Sync always said "In Progress" but never synced (that's another bug). I was able to find the sync-log in his Fennec profile dir and he emailed it to me directly, without using Fennec to view it. Steps I performed: 1. Opened Fennec. Went to about:config. 2. Set services.sync.log.logger.engine.history to Trace. 3. Set services.sync.log.appender.debugLog.enabled to True. 4. Set services.sync.log.appender.debugLog.maxSize to 16777216. 5. Left the about:config screen. 6. Force quit Fennec. 7. Started Fennec. 8. Clicked "Sync Now" in preferences, waited for a minute. 9. Went to about:sync-log. At this point, the page tried to render, succeeded for a moment, I tried to scroll, it froze, repainted, and then crashed to gray. I was able to get to the tabs list on the left and close the crashed tab. Later inspection showed that about:sync-log was trying to render a 2.7MB log. (Incidentally, that is the expected size of that logfile for a user with lots of history entries to sync.)
Crash stack? Still happen?
