Send_data crashing WEBrick under specific conditions


I have an action with the following view, which seems to be crashing

<%= render_component :controller => ‘picture’, :action => ‘show’, :id =>
1 %>

<%= render_component :controller => ‘picture’, :action => ‘show’, :id =>
2 %>

The two components (code below) result in image tags that call an action
that returns the image data. If I remove the tag, this does not occur. Nor does it
occur if both components are given the same id argument (display the
same image).
Often the page will load the first time, but upon refresh the two images
from the component calls will not display and WEBrick will stop

The ‘show’ action:
def show
@picture_id = params[:id]
render :layout => false

The ‘show’ view:

The ‘picture’ action:
def picture
picture = Picture.find(params[:id])
send_data(, :filename =>, :type => “image/jpeg”,
:disposition => “inline”)

The ‘data’ method in the Picture class
def data + “/” + get_filename).first.to_blob

Does anyone have a clue as to why this may be occuring? Thanks.
