VMWare Remote Console Plug-in Unrecoverable Error: (mks)

I'm having some weird problem with Firefox 3.0.4 under Ubuntu Linux. My test server runs inside VMWare server version 2.0. It was working fine with my Laptop. But with my desktop it started to dump errors for me. when I try to open the console of a virtual machine I have following error:

There is no bug fix provided. However, this thread provided some hint for me:

The log file indicates that the plugin is crashing in a color conversion routine.

So I went ahead and updated my X.org configuration from 1 Billion colors (depth 30) to to 65,536 color (depth 16). Finally, just restarted my X and bingo, I was able to launch remote console plug-in. My updated x.org:
