Hi list.

Some days ago I’ve updated my kubuntu and my ruby server just stop, I  
decided to run a “gem update” and everything seem to be ok.

but i get to this line of code:

send\_data(g.paint(XMAX_MULT,YMAX_MULT,MULT).to\_blob, {:type =\>  
‘image/jpeg’,  
:disposition =\> ‘inline’})

which used to work before, and now it’s throwing an error:

no decode delegate for this image format `' app/controllers/generate_controller.rb:37:in`to\_blob’

I assume it’s a matter of updating, so I run ‘gem update rmagick’ and it  
says:  
Successfully installed rmagick-2.5.0

Stop the server, run again, and I have the same error.

Any help?
