###!!! ASSERTION:
XPConnect is being called on a scope without a 'Components' property!

This is pretty much always bad. It usually means that native code is
making a callback to an interface implemented in JavaScript, but the
document where the JS object was created has already been cleared and the
global properties of that document's window are *gone*. Generally this
indicates a problem that should be addressed in the design and use of the
callback code.

I don't see this on Linux.  Does anyone see this currently on Windows (or any
other platform)?  If so, please give exact steps to reproduce it.

i just hit this while quiting (freebsd, cvs build from yesterday)
solaris sparc + w2k x86 = all/all.

Attachment: log

here's a log, please excuse my foibles, i still don't know what to look for
when it comes to things like this.

It looks like the CEvent failures and the Components assertions are related.

dbradley said that there is some dom logic to 'clean' the global object.

what we're dealing with here is obviously an edge case, so anything is possible
:).  After he mentioned that, i looked back and noticed that indeed there is a
mention of /dom/ right before this problem happens :-)

Is this still happening?

Comment 6

[timeless]

i haven't used a cvs build in a while

Comment 7

[Samuel Sieb]

This doesn't seem to happen anymore.  Reopen if you see it.
