Crash in gecko-mediaplayer-wmp.so Windows Media Player module when Flashblock installed

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install gecko-mediaplayer package in Ubuntu
2. Install the Flashblock extension: 
https://addons.mozilla.org/en-US/firefox/addon/433/
3. Go to http://www.polskieradio.pl/9,Trojka

What is the expected output? What do you see instead?
It should display the page. It crashes the whole Firefox

What version of the product are you using? On what operating system?
Firefox 3.6.13 64-bit on Ubuntu 10.04 (Lucid) 64-bit

Please provide any additional information below.
gecko-mediaplayer crashes the whole Firefox in it's gecko-mediaplayer-wmp.so 
Windows Media Player module, for example when going to this site:
http://www.polskieradio.pl/9,Trojka
Disabling it in plugins tab of Tools->Add-ons, other gecko-mediaplayer plugins 
seems fine so far.

I discovered this issue when I used Flashblock, disabling Flashblock 
surprisingly helps so I thought it's their bug but it seems the other way. 
Almost all of my Mozilla crash records on this site look like this one:

Can you retest with the current version 1.0 of gecko-mediaplayer and 
gnome-mplayer.

Nevermind about testing 1.0. I tested with SVN and found a couple of NULL 
pointer bugs. I fixed them, and the change is in SVN r420
