Comment 1 Rolf Bjarne Kvinge [MSFT] 2012-06-20 08:39:58 UTC
Is this reproducible or does it just happen once in a while?
Comment 2 Joseph Hanna 2012-06-20 09:15:37 UTC
It only happened once, but the error told me to "Please fill a bug report at http://bugzilla.xamarin.com", so I did.

Comment 3 Sebastien Pouliot 2012-06-20 14:45:06 UTC
This case was fixed after 5.3.4 release. Bug #5776 [1] describe a workaround (to use the older upload code).
