How to reproduce: Install the 1.3.1-b24 version of the Java plugin for Linux. Start mozilla. Visit about:plugins Visit http://www.javasoft.com/ Crash with 'Null Plugin Manager' error. Crashes with milestone 0.9.4. Talkback incident ID - TB35466527Q With nightly build Mozilla/5.0 (X11; U; Linux i386; en-US; rv:0.9.4+) Gecko/20010912 Talkback incident ID - TB35466724Y With nightly build Mozilla/5.0 (X11; U; Linux i386; en-US; rv:0.9.4+) Gecko/20010916 Talkback incident ID - TB35467339M

I also crash reproducing these steps with build 2001091421 on RH6.2 Linux and JRE 1.3.1-b24. Going directly to http://java.sun.com/ does not crash though. Respecting the steps is important in order to reproduce the bug.

Confirm on linux 2001091606 trunk. This is not limited to Java. going to macromedia.com for flash content after this will crash also. My talkback ID is TB35480162K (from flash).

From duped Bug 99986: "If I use the Help pulldown and select 'About Plugins' and then go to a site that requires one of my loaded plugins, my browser explodes. My current plugins are Real Player 8 basic, Shockwave 5.0 r47, and JRE 1.3.1 b-24. I experience no problems with my plugins if I don't use the Help menu."
