What were you trying to do?
	Run NetScrape for more than 1 minute.

What's wrong:
	NetScrape 4.61 is buggier than ever.  Please
   browse the following sequence of URLs to make it crash hard.

What should have happened:
	It should not have crashed.

Please describe any relevant documentation references:
	
In general, I've noticed that the new Netscape is a _lot_ less
reliable than the previous version (4.05), which was pretty bad itself.
Often, it crashes suddenly when I bring up a page with an inline GIF.  
Nothing fancy, just a large-ish GIF.   Usually this happens randomly and
I just start a new one and curse Mozilla as a BPOS while waiting for that.
Lately I found a reproducible path to a crash.

So, here's a sequence that is guaranteed to crash netscape hard at
least in my environment:

Start a fresh Netscape 4.61 (you may or may not need an SGI
and Athena 8.2 environment to reproduce the bug).

Browse the following URLs in sequence -- this reliably crashes it!

https://memory-ultra/checklist.html
(choose the link to "5.Database Comparing Old & New CSTR Collections.")

https://memory-ultra.mit.edu/cgi-bin/cstr-compare.pl
(Check the green boxes next to "Scan Record or TIFFs present in Old coll",
"Failed in the CD-ROM reprocessing cycle", and 
"New collection has PostScript or PDF format of document".  
Then click the "Match these .." button.)

https://memory-ultra.mit.edu/cgi-bin/cstr-compare.pl?S=S&f=f&p=p&output=html&submit=Match+these+Records
(Now choose the "Yes" link in the "New Collection" column, "AIM-1280" row,
which should take you to..)

http://ncstrl.mit.edu:8088/Dienst/UI/2.0/Describe/ncstrl.mit_ai%2fAIM-1280
(Fill in 31 in the page box and click "Display Page", which brings up:)

http://ncstrl.mit.edu:8088/Dienst/UI/2.0/ShowPage/ncstrl.mit_ai%2fAIM-1280?npages=59&format=inline&page=31
(Now it gets complicated.  With the mouse in the middle of the page 
image, hold the right button to bring up the menu and choose "Copy Image
Location".  Then, I use the meta-L key to bring up the "Open" dialog
box -- probably choosing it off File in the menubar would do the same.
Use the X paste feature (mouse-middle, usually) to paste in the URL of
the image.

EDIT the image URL to change it from 

  http://ncstrl.mit.edu:8088/Dienst/document_root/AIM/1200-1299/AIM-1280/AIM-1280.100x5cLZW/AIM-1280.100x5cLZW.pg0031.gif

to 
  http://ncstrl.mit.edu:8088/Dienst/document_root/AIM/1200-1299/AIM-1280/old-inline/AIM-1280.100x5cLZW.pg0031.gif

(just change /AIM-1280.100x5cLZW/ to /old-inline/)

Hit <return> to bring up that URL, and Netscape will vanish before your eyes.

If I do _anything_ different in this sequence, sometimes it lives,
so this looks like a subtle bug.
