NSPlugin crashing Firefox 7 in a VNC session

[AndrewR]

This only occurs when running in a vnc4server session. Problem is new with FIrefox 7 (7.0.1). Running normally on the desktop, it's not crashing.

Steps to reproduce:
Start new vnc server - ex: `vnc4server -geometry 1024x768`
Connect to vnc. I am doing this remotely through an ssh tunnel.
Run Firefox 7.0.1 with adobeflash-plugin installed.
Visit a page with Flash, and the browser crashes.

Error from console:

Hi Andrew,

Is this issue reproducible with nspluginwrapper 1.4.4 from oneiric?

[AndrewR (andrew-awrsolutions)]

I would like to try the updated version from Oneiric, but I am having problems getting it installed. Nspluginwrapper has an AMD64 version for Oneiric, but it depends on nspluginviewer, which only has an i386 version. I downloaded the source code, but I am having problems building it.

You need to enable multiarch on your system as described at

I have upgraded to Oneiric and can confirm that this is still occurring with NSPluginWrapper 1.4.4.
