Status: VERIFIED WORKSFORME

(Core Graveyard :: Plug-ins, defect)

Description

[Jeff Pudwell]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
BuildID:    2002021708

When using the sample scriptable plugin in the mozilla source tree, the browser 
crashes after pressing the Refresh button. Worked find in 0.9.5 & 0.9.6 but now 
crashes the browser in 0.9.7 & 0.9.8.

Reproducible: Always
Steps to Reproduce:
1.Load a page in browser with a scriptable plugin (XPConnect)
2.Call a method on the scriptable plugin
3.Press the Reload current page button and the browser will crash.
Note: If it doesn't crash the first time, repeat steps and it will eventually 
crash.


Actual Results:  The browser throws up an exception and crashes.

Expected Results:  Should Reload the current page with the scriptable plugin.

Here's the stack from the crash:
