If you have multiple tabs open, and close more than one of them quickly (using
the holding down the keyboard shortcut for instance,) several errors appear in
the JavaScript Console.

Reproducible: Always

Steps to reproduce:

0. Have javascript.options.showInConsole set to true.
   Open up the JavaScript Console (Tools > JavaScript Console) and Clear all the
errors.

1. Open up multiple tabs (8 or more is good, preferably with about:blank loaded
in each.)
2. Hold down the keyboard shortcut for 'Close Tab' (found in File > Close Tab.)
3. Open up the JavaScript Console (Tools > JavaScript Console,) and go to Errors.

Actual Results:

JavaScript Console showed multiple errors.

Expected Results:

JavaScript Console should not have shown any errors.

The error was:

Error: uncaught exception: [Exception... "Component returned failure code:
0x80004005 (NS_ERROR_FAILURE) [nsIDOMXULElement.boxObject]"  nsresult:
"0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
chrome://global/content/bindings/browser.xml :: get_docShell :: line 0"  data: no]

I've seen this on windows XP on a recent trunk build, so marking platform all.

I thought maybe it had something to do with session restore, but this bug is from 2005-04-04, which is way before dietrich's work.

Can you still reproduce this issue? I can't in Firefox 3.5.3, which is what I have open currently...
