audacity ddclient.cpp assert m_window failed

Whenever I start Audacity, I get an assertion failed pop up box. This is merely annoying, as you can select continue, and Audacity keeps running.

ASSERT INFO:
../src/gtk/dcclient.cpp(2038): assert "m_window" failed in DoGetSize(): GetSize() doesn't work without window
