134996 - Composer uses about:blank as its base URL. which causes errors in nsImageLoader::Load

Status: RESOLVED DUPLICATE of bug 166166

(Core :: Layout, defect, P2)

Description

this was split off from http://bugzilla.mozilla.org/show_bug.cgi?id=102585

Composer uses about:blank as its base URL. This is not a valid URI for forming
URL's for images. Although we do not crash because we are handling the ERROR
return codes which result from using a bad base URI this problem should really
be fixed.  

The composer window will show garbage when switching between modes because the
body is transparent.

In addition, this results in "About: Blank" getting printed as the document
location when printing from Composer.
