It's interesting. The "fear" of firewall interaction was the reason to
use QLocalSocket and not QTcpSocket for interaction with the debugged
program. Looks like your firewall even tries to block this... Is there
no way to specify exceptions?

You could try to switch off "Debug -> Use Custom Display for Qt Objects"
and "Build&Run -> Build Settings -> Link Debugging Helper" and see if
this makes a difference.
