650306 - This URL makes Firefox 4.0 crash

Status: RESOLVED WORKSFORME

(Plugins Graveyard :: VLC (VideoLAN), defect)

Description

[Hervé Cauwelier]

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0) Gecko/20110321 Firefox/4.0
Build Identifier: Mozilla/5.0 (X11; Linux x86_64; rv:2.0) Gecko/20110321 Firefox/4.0

I use Flashblock when I click to load the applet, Firefox crashes.

I wouldn't worry about the usual Flash **** if Firefox was not supposed to crash because of a plugin anymore.

Reproducible: Always

Steps to Reproduce:
1. Go to the URL
2. Start the applet if Flash is blocked

Actual Results:  
Firefox crashes instantly

Expected Results:  
I don't think I saw such a crasher since plugins run in a different process.

This is the branded Firefox on Archlinux x86_64.

This is printed on the console when the page is loaded:

*** NSPlugin Viewer  *** WARNING: unhandled variable 18 (<unknown variable>) in NPN_GetValue()

This is printed when Firefox crashes:

firefox: symbol lookup error: /usr/lib/mozilla/plugins/libvlcplugin.so: undefined symbol: NPP_Initialize

Strange, it's a Flash video.

Have you submitted any crash reports? If so then look in about:crashes and post the id:s/links here.

Also try to run in Safe Mode and see if that makes any difference:

Peeking into the page source the video seems to be a mix of Flash and Silverlight and I've no idea why the vlc plugin gets involved.

Do you still get crashes if you disable the vlc plugin in the Add-ons Manager?

this is probably a bug in vlc (which is probably pretending to be flash player -- see about:plugins)

I'm afraid the page changed, so I cannot reproduce the bug. I have to close it. Sorry for the noise.
