Created an attachment (id=399140)
 --> (http://bugzilla.novell.com/attachment.cgi?id=399140)
Sample that describes how to download an image from the internet that is
crashing

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)
AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.44 Safari/534.7

What i'am trying to achive is download an image from an url to my device, i
searched in google for an tutorial for monodroid but without any results. So
then i searched by an tutorial for android, in general, and i found this
sample:
http://www.helloandroid.com/tutorials/how-download-fileimage-url-your-device
(in java). 

I already implemented it using monodroid, but after i run it in the emulator it
crashes, after executing the line "InputStream inputStream =
urlConnection.InputStream;".



Reproducible: Always

Steps to Reproduce:
1.Open the Solution attached.
2.Run the app.
Actual Results:  
I get the next message in the emulator: "The application
AndroidDownloadImages.AndroidDownloadImages) has stopped unexpectedly. Please
try again."

And this is the message i got in Android Device Logging:

Expected Results:  
The app should not crash, and the bufferedInputStream's var should contain the
image stream.
