What user interface are you using? VNC? SDL? GTK?

This is gtk interface.

However, the function on line 40 os spapr_vty.c looks really insane.

It asserts that it is not given more data to input in a ring buffer than
is size of the buffer and then stuffs all the data in regardless of the
amount of data already present.

It should probably loop or one of its callers but I did not find a
decent comparable piece of code to cut and paste whatever callbacks are
needed for the other side to consume the bytes.

OK, seems like you need to compile QEMU with CONFIG_VTE enabled (i.e. with the vte-devel packages installed before running configure) to get copy-n-paste support in the GTK interface, that's why I was initially not able to reproduce this issue.
Anyway, now I can trigger the assert(), too, and I've suggested a patch here:

FWIW, the crash should be fixed by this commit here:
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=7bacfd7f7289192c83330
(but we still need to fix the gtk side, too, to only send as much characters at once as the receiving side can take)
