(Resending this as I wasn't subscribed before and I think my message didn't make it through)
I've installed Boxes through the AUR on an up-to-date Arch
system. Whenever I try to start up a VM, it works for a moment, then the
display goes away and I'm left with a blank starting screen again.
These seem to be the relevant lines of Console output:
