91253 - crash when displaying about:plugins and then using plugins

Status: VERIFIED DUPLICATE of bug 86591

(Core Graveyard :: Plug-ins, defect)

Description

[Chi-Thanh Christopher Nguyen]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:0.9.2+) Gecko/20010717
BuildID:    2001071710

When entering about:plugins into the URL bar before any plugins are loaded, and
then visiting a page that uses these plugins, Mozilla will crash saying
"Internal error: Null plugin manager"

This occurs on Solaris 20010716(trunk) and 20010717. 


Reproducible: Always
Steps to Reproduce:
1. Launch Mozilla
2. Enter about:plugins into the URL bar
3. visit a page that uses the plugins, eg. http://java.sun.com/ (Java Plugin) or
http://www.storage.ibm.com/ (Flash)

Actual Results:  Browser will crash with error message "Internal error: Null
plugin manager"

Expected Results:  Plugins should be loaded and page displayed.

This does not occur when the plugins have been loaded before, ie. go to
http://java.sun.com/ then about:plugins then http://java.sun.com/ will not crash
Mozilla.

Hmm. This looks like a regression. With
Mozilla/5.0 (X11; U; SunOS 5.8 sun4u; en-US; rv:0.9.1) Gecko/20010608
there is no problem. This might be some kind of reincarnation of Bug 65802
although the error message differs.
