Steps to reproduce:
1. Start Firefox with clean profile.
2. Enter panorama, create a second group and populate it with 3 tabs.
3. Close a tab from second group using scroll button from the mouse.
4. Go to tab view and press "Undo Close Tab"
5. Go to panorama and close tab using scroll button from the first group.
6. Open group of the closed tab and from context menu select "Undo close tab"

Actual results:
 - a new empty tab is opened, panorama has UI issues (see Screenshot 1) and by selecting a tab from the other group you can observe that the tab organization is messed up

Expected results:
 - previously closed tab is reopened in current group

I'm sure this is a dupe of bug 628270. There should be an error in the console saying:

Error: uncaught exception: [Exception... "'[JavaScript Error: "aTabs[ex - 1] is
undefined"

Yes, that is the error I get in the console:

Error: uncaught exception: [Exception... "'[JavaScript Error: "aTabs[ex - 1] is undefined" {file: "resource://gre/components/nsSessionStore.js" line: 2463}]' when calling method: [nsISessionStore::undoCloseTab]"  nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)"  location: "JS frame :: chrome://browser/content/browser.js :: undoCloseTab :: line 12148"  data: yes]

Did not know issues are correlated.
