following a link to a non existing newserver/message makes mozilla go wild (100%
cpu usage, mouse pointer flickering)
leaving nothing else than to kill mozilla program.

Reproducible: Always
Steps to Reproduce:
1. Open browser window
2. click URL


Actual Results:  100% cpu usage, mozilla does not repond anymore

Expected Results:  some kind of error message

I encountered this when clickin on a link on the mozilla 1.0 branch thinderbox
page. (link to Branch Checkin Policy:
news://news.mozilla.org:119/[e-mail]

news.mozilla.org is not reachable on my machine. But URL above shows same
problem.  (doesnotexist.mozilla.org)

Dont' know what to tell you - this worksforme with build 6-5-2002 on Windows 2000.

All I get is a quick JS alert that says, 'doesnotexist.mozilla.org could not be
found.  Please check the name and try again.'

Retried at home (different PC, also win2000)
This time with Mozilla v1.0 ID:2002053012

I am seeing the same bug.
Clicking the URL   -> 100 % cpu usage.  (after some trying, It is possible to
get the back button to work, then cpu usage goes normal again. You cannot do
anything than trying (hard) to press back)

But you're not seeing this ? Weird.

Are you on dialup or broadband?  Any proxy servers in the way?

It could be something in the networking code, which is failing to pass back some
event saying 'domain not found' in the correct time.

I'm seeing this both at work and at home.
home: dialin, no proxy server
work: company network, proxy server

Comment 6

I don't know what changed but...
this seems to work now (mozilla 1.2a on windows 2000)
steps:
1) click url

result:
error box is shown  (as expected)

I think the bug can be closed
