When attempting to load a XUL page that tries to load the
chrome://navigator/skin/ CSS under FireFox, all FireFox instances either die, or
hang indefinitely.  This has been tested with FireFox 0.9.0 and CVS HEAD from
Tue Aug 10 14:44:10 PDT 2004.  When run with debugging enabled, the following
error message is outputted repeatedly until the application crashes:

###!!! ASSERTION: content sink not found!: 'mSink', file nsExpatDriver.cpp, line 458
Break: at file nsExpatDriver.cpp, line 458

A sample XUL page that exhibits this is attached.

Reproducible: Always
Steps to Reproduce:
1. Create a XUL application that includes chrome://global/skin and
chrome://navigator/skin
2. Load it in FireFox...Crash
3. Load it in Mozilla...the application runs.

Actual Results:  
The application either crashed outright, or hung.

Expected Results:  
The XUL page should have loaded.

Michael: Could you provide TalkBack incident ID, better from FF093?

Comment 4

[Michael A Nachbaur]

Most of the time FireFox only hangs; it crashes intermittently.  So, of course, the one 
time I try to get it to crash to send in an incident report...I couldn't. 
 
I manually ran the talkback agent and sent in incident ID TB536601Y anyway.

Manually created incidents are useless, because doesn't contain technical
details about crash.

highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
