I runned this for 100 times and Mario for 50, and it did't reproduced. We should check on an affected machine once it fails again.

I wasn't able to reproduce it yet, will keep an eye on future failures and investigate the CI machines when it fails again.
Didn't happen since 11/24, please reopen if needed.

This just failed again on 27.0 Beta, de: http://mozmill-release.blargon7.com/#/functional/report/94e33fe3d7ec0be6dbbfa0a702915e5c
This has started to fail more often. Updated the URL field since newer failures didn't show up anymore 6 failures today already: http://mozmill-daily.blargon7.com/#/functional/failure?branch=All&platform=All&from=2014-01-22&test=%2FtestSessionStore%2FtestUndoTabFromContextMenu.js&func=testUndoTabFromContextMenu We should try to figure this one out and fix it. Tempted to raise priority to P1 if the failure rate maintains.
I can't reproduce this locally, but it has a failure rate on CI of roughly 90% right now. We should skip now and find a fix. Will have a skip patch shortly.
Skip patch due to recent failures until we can come with a fix.

I tried to reproduce this locally on Ubuntu both with testruns and about 200 single test runs (mozmill -t) but wasn't able to reproduce. I took offline mm-ub-1310-32-3 and will try to reproduce it there in order to figure out what is going on.
Ran the test today about 600 times and only had 1 failure. I will continue testing tomorrow and hopefully find a way to reproduce it more constantly.
When I run those tests I can clearly see an error printed to the browser console and to the terminal: console.error: Message: TypeError: docShell is null Stack: SessionHistoryInternal.collect@resource://app/modules/sessionstore/SessionHistory.jsm:48 this.SessionHistory<.collect@resource://app/modules/sessionstore/SessionHistory.jsm:28 SyncHandler.collectSessionHistory@chrome://browser/content/content-sessionStore.js:200 TabStateInternal._collectSyncUncached@resource://app/modules/sessionstore/TabState.jsm:329 TabStateInternal.collectSync@resource://app/modules/sessionstore/TabState.jsm:242 this.TabState<.collectSync@resource://app/modules/sessionstore/TabState.jsm:57 ssi_onTabClose@resource:///modules/sessionstore/SessionStore.jsm:1417 ssi_handleEvent@resource:///modules/sessionstore/SessionStore.jsm:765 This seems to be a regression in Firefox under specific circumstances and looks like bug 961861. I will ask over there.
Status: REOPENED → NEW
This problem should have been gone now with the backout of the patch from bug 961861. Mario, can you verify this? If that is the case let us unskip this test.
I have ran the single test 1000 times (2x500 runs) and we haven't had a single failure, uploading unskip patch so that we re-enable the test.
