Can't import private key to GnuPG 2.1.1 on Windows 8 x64

[Jesper Hess Nielsen]

Hi all!

I just installed the latest GnuPG 2.1.1 on my main Windows PC and tried
to import my private key. However, it fails with a message from gpg-agent:

gpg: key 0x416C5A0DD9FA2EE5/0x416C5A0DD9FA2EE5: error sending to agent:
End of file
gpg: error building skey array: End of file

In the Windows Event Viewer I get the following notification of a crash:

Faulting application name: gpg-agent.exe, version: 2.1.1.2240, time

Any ideas what might be going wrong here?
