Turns out they're blocking this intentionally. Their reply was:

"This is known and intentional. We specifically block that because of 
abuse that has come from that user-agent (being default also means that 
malicious behavior often uses that user-agent as well). You should set 
the user-agent to be something that includes your project name and/or 
URL so we know who to contact if we start to notice abusive behavior 
from your software."

Perhaps Qt should add something to the user-agent string. Maybe:

   Mozilla/5.0 Qt/x.y.z
