Quodlibet freezes on starting

Binary package hint: quodlibet

After upgrading to Feisty, quodlibet freezes consistently on starting and can only be killed forcibly (kill -9 1234).

When I run it I get this output:

Quod Libet is already running. #If I remove ~/.quodlibet/control beforehand, I don't get these two lines. It's not actually running.
Unable to write to /home/joseph/.quodlibet/control. Removing it.

/usr/share/quodlibet/qltk/dbus_.py:11: DeprecationWarning: The dbus_bindings module is deprecated and will go away soon.

dbus-python 0.80 provides only a partial emulation of the old
dbus_bindings, which was never meant to be public API.

Most uses of dbus_bindings are applications catching the exception
dbus.dbus_bindings.DBusException. You should use dbus.DBusException
instead (this is compatible with all dbus-python versions since 0.40.2).

If you need additional public API, please contact the maintainers via
<email address hidden>.
