RDoc parses binary files

[postmodern]

Tested rdoc 4.0.0 on Ruby 2.0.0-p0 and got this warning:

unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/sinatra/images/404.png, skipping
unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/sinatra/images/500.png, skipping

Reproduced this issue when installing sinatra-1.3.5 using

$ gem install sinatra

I have this problem.

I have this problem with ruby 1.9.3p392 on Linux Mint. When installing Sinatra it gets to this point and hangs:

Installing ri documentation for sinatra-1.4.1...
unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/sinatra/images/404.png, skipping
unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/sinatra/images/500.png, skipping

Installing sinatra-1.4.1 and I hit this too.

After running:

sudo gem install sinatra

My ruby --version reads:

ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin12.2.1]

And here's what I get:

Fetching: rack-1.5.2.gem (100%)
Fetching: rack-protection-1.5.0.gem (100%)
Fetching: sinatra-1.4.1.gem (100%)

Then the gem install seems to stall.
