In case anyone else has this issue: It was basically what Antonio said, the USER_WORD_0 was set wrong by Arduino. The factory setting is 0xD8E0C7F9, but it needs to be set to 0xD8E0C7FF. In Atmel Studio one can do that by changing the fuse-setting USER_WORD_0.NVMCTRL_BOOTPROT from 0x01 to 0x07.
If we find a way to do that automatically with openocd we'll post it.

It might be possibile to do that with OpenOCD, but frankly I don't know how.
