Subject: No longer able to add iptunnel interface to bridge?

After rebooting my router/firewall (Debian Wheezy with debian 3.2.41-2 
kernel), I am no longer able to add an iptunnel to a bridge interface.

The iptunnel is configured like this:

iptunnel add TUNNEL mode ipip remote x.x.x.x local y.y.y.y ttl 32
ifconfig TUNNEL z.z.z.z netmask 255.255.255.254 up

and this is what strace shows when I try to do "brctl addif test TUNNEL":

ioctl(3, SIOCBRADDIF, 0x7fffafba64c0)   = -1 EINVAL (Invalid argument)
ioctl(3, SIOCDEVPRIVATE, 0x7fffafba64c0) = -1 EINVAL (Invalid argument)

I have no idea if I might have changed something in userspace by misstake, 
or if there has been a change in the kernel since last reboot. The same 
machine has a different bridge with an L2TPv3 tunnel added, this works 
fine.

I understand that the info here is not much to go on, but I am unsure what 
else to attach. Plese ask for further info and I shall provide it!

Best regards,
Tomas
