content.location is undefined when passed as a replacement argument to string::replace. This doesn't happen with other properties of content like content.name. Also it is not console-specific as I discovered this behavior in my extension.

Reproducible: Always

Steps to Reproduce:
Enter
alert("(a)".replace('a', top.opener.content.location)); alert(top.opener.content.location;
into the Error Console
Actual Results:  
First pop-up says (undefined), second one gives correct url

Expected Results:  
Both pop-ups should give the same result

Tested on a clean install, doesn't happen with latest Firefox/3.6

Looks like a JavaScript bug to me. I think location's toString() method [1] should be called.

Could be xpconnect related problem.

I am pretty sure I fixed this on the tracemonkey branch. This should be merged over into m-c soon. CC'ing sayrer to make sure this is being tracked.
