97498 - Continuos error messages stream in JavaScript Console

Status: VERIFIED DUPLICATE of bug 85831

(SeaMonkey :: UI Design, defect)

Description

[Andrea]

How to reproduce:

- Open the JavaScript Console
- Type in: var variable = window.open ('file:///path/filename.html')
  where path/filename.html is an existing local HTML file
- Let the new window popup, and then go back to the JS Console
- Close the JS Console
- Reopen the JS Console
- Type in: alert (variable.title)

The JS Console starts to write a never-ending stream of
"Error: this.console.appendItem in not a function
 Source: chrome://global/content/consoleBindings.xml#console-box.init()"
errors and the Mozilla CPU usage skyrockets. Even closing
the JS Console. Even when the JS Console is reopened again
the errors are still continuosly reported.

Closing all Mozilla windows (e.g. pressing Ctrl+Q in Navigator)
closes all the visible windows, but does not make the Mozilla
task die (with the turbo mode turned off), which continues to
have an high CPU usage.

P.S.: I filed this bug to hewitt under the rginda advice

Oops, I forgot to say I found this problem with Mozilla 0.9.3 release.

CPU utilization is very high even after closing JS console.  closing all windows
doesn't leave any rogue mozilla-bins, though.
