Description Sebastien Pouliot 2011-12-07 09:22:00 UTC
when I start MonoDevelop I get a dialog showing:

Unhandled Exception. MonoDevelop will now close

System.NullReferenceException: Object reference not set to an instance of an object
  at Xamarin.Ide.Updater.DownloadService.Download (System.Object o) [0x00000] in <filename unknown>:0 


1. Clicking on OK does *NOT* close MonoDevelop - so the message is wrong. Everything seems to work except...

2. Updates do not work anymore, either by the menu or by the status bar icon;

2.a. It shows that Mono for Android 4.0 is downloading (progress bar empty) but it can't be paused. 

2.b. MonoDevelop 2.8.4 is shown as pending but there's no way to download/install it;

2.c. The button "Details" works and show the text about both updates.

Lluis, Michael,

Can you weigh in this bug, who should own this?
Comment 2 Mohamed Saif 2011-12-12 23:44:26 UTC
I have the exact same issue.
Note: I've just purchased Mono for Android. I have already Monotouch. The problem started for me after installing Mono for Android.
Comment 4 John Heerman 2012-01-24 15:46:10 UTC
Still experiencing this problem.  Current workaround is to manually download and apply updates.
