I figured out my problem here, but I don't think it explains the entire
issue. The problem was that some files where not uploading as image files
and instead the @uploaded_file was a String. If I check the class of the
file first I can work around the problem. I still don't think it makes
sense that there are no exceptions thrown.
Here's a simplified look at the code in my rails model.
if @uploaded_file.class == File || @uploaded_file.class == Tempfile
begin
img = Magick::Image::read(@uploaded_file.path).first
self.data = @uploaded_file.read
self.attributes = {:data_format => img.format, :height => img.rows,
:width => img.columns, :filesize => img.filesize}
return true
rescue
# there was an error
end
end

i have a rails app with a form that allows uploading an image file. I
take the image file and read it into rmagick to verify that it's an image.
For some reason I can't catch an exception thrown by rmagick inside the
app. After an invalid image file is uploaded the process just hangs. I
have to kill mongrel and restart to use the app again.
img = Magick::Image::read(@uploaded_file.path).first
This line above should throw a Magick::ImageMagickError exception. I've
confirmed this with a simple ruby script.
I've tried adding breakpoints and as soon as this line is reached there's
no coming back, even the breakpointer hangs.
I pasted the method from my active record class here:

Does anyone have any ideas?
