Status: RESOLVED WORKSFORME

(SeaMonkey :: General, defect)

Description

[David Hagood]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a1) Gecko/20051121 MultiZilla/1.8.1.1c SeaMonkey/1.5a
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a1) Gecko/20051121 MultiZilla/1.8.1.1c SeaMonkey/1.5a

Certain pages cause Seamonkey to get caught in a loop with 100% CPU load - for example, http://www.latimes.com/news/nationworld/world/la-fg-cocola12apr12,0,5775549.story?coll=la-home-headlines

The UI goes completely unresponsive - clicking on window close will NOT work - the only way out is a SIG(HUP|TERM|KILL) to the process.

Reproducible: Always

Steps to Reproduce:
1. Load the specified URL
Actual Results:  
CPU load goes to 100%, Seamonkey stops responding to ALL events.

Expected Results:  
Page should load.

Examining the code shows the page tries to fetch some advertising from brt.trb.com - blocking JS and images from them seems to have allowed the page to load.

worksforme with linux seamonkey trunk build 2006041318
can you try with a clean profile?

or, while it's frozen, do:
% kill -SEGV _pid_of_seamonkey_

this should trigger talkback and we can see the stack it had while it was frozen.

OK, I forced the condition - allowing image loads from brt.trb.com is what does it.

The TB is TB17583556E.

Just loaded the latest nightly, and am unable to reproduce.
