It is my understanding that if the first argument to windows.open() is an empty string or null, then a new window should be created but no document should be loaded. M11 attempts to load a document with an empty name. (Which is likely to be an index.html file, a directory listing, or an error page.)

Reassiging to the DOM component. window.open isn't in the core JavaScript engine.

In an attempt to get my bug list in order again, marking all the bugs I have currently as ASSIGNED.

Reassigning to danm, since he's now defacto owner of window.open().

window.open() without parameters should open a new, blank window. Mozilla doesn't. Added bonus: mozilla will refuse to shut down after attempting to open such a window. Neato.

I've applied the patch submitted above by bissiri; it explicitly skips the URL load if no URL parameter was specified. Fixes the original complaint and also solves the secondary symptom I mentioned just above (app refuses to quit). Thanks, masked man!

Oops. Patch was actually very evil. Backing out for now.

*** Bug 22487 has been marked as a duplicate of this bug. ***

After resubmitting a second patch from Matthew, we seem to get all the good behaviour without the evil. Not really sure what went wrong last time. Perhaps I messed up a brace or something in my last attempt. Seems good this time. Sorry for the confusion.
