It seems like bug 644995 may also be involved on win64, or at least that the IPC mechanism between paramiko and pageant needs fixing somehow.
As a workaround, could try trading for a different set of issues (see bug 414743) by setting BZR_SSH=plink after manually connecting to accept the server fingerprint.
