Description of problem:
The RedHat 7.3 errata for glibc, glibc-2.2.5-40, breaks plugins for Netscape
4.x. If a page with a plugin is encountered (e.g. java, realplayer), then
netscape core dumps.

Both downloaded (from netscape) and RedHat provided Netscapes crash. Using glibc
2.2.5-39 works fine.

 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Upgrade glibc to 2.2.5-40
2. Run netscape
3. Go to http://sunsite.org.uk/
	

Actual Results:  Netscape core dumps

Expected Results:  Netscape starts plugin
