I often get a web page when ever I try localhost:3000 with the  
following message:

Internal Server Error  
private method `gsub!’ called for #Class:0xb6d5d764  
WEBrick/1.3.1 (Ruby/1.8.7/2010-01-10) at localhost:3000

I get this thing after I upgraded to Ubuntu 10.04, is some one facing  
this same problem. Is there any fix for this?

Thanks in advance.
