I apologise because I am coming to this question very late and after not
paying attention to the earlier messages in the thread. However: That
looks a lot like what happens when a link local address is used with no
scope qualifier.

Here it is with plain old ping to one of my local machines:
kauer at karl:~$ ping6 fe80::209:6bff:fe30:3e92
connect: Invalid argument

But:

kauer at karl:~$ ping6 fe80::209:6bff:fe30:3e92%wlan0
PING fe80::209:6bff:fe30:3e92%wlan0(fe80::209:6bff:fe30:3e92) 56 data bytes
64 bytes from fe80::209:6bff:fe30:3e92: icmp_seq=1 ttl=64 time=6.92 ms
[...]

So if your source address is a link local address, try adding a suitable
scope qualifier.

Again, my apologies if this has already been suggested and discarded.

Regards, K.
