ubun2^beta

Getting the following error while i was browsing a website
 
Sorry, the program "npviewer.bin" closed unexpectedly
 
npviewer.bin crashed with SIGSEGV
 
Looks like it has to do something with the flash player library libflashplayer.so 
 
I am getting this error after upgrading to ubuntu 9.10. This is happening on a 64 bit machine. How to fix this?
