bug#10169: a simple interrupt evokes abort?! (but only with (require 'saveplace))

I can reproduce it indeed with Debian testing's emacs23 as well as with
the current trunk.

I have to be careful to hit C-c before Emacs actually opens the frame
(i.e. interrupt it during startup), otherwise it exits cleanly.

Can't investigate further right now, so if anyone wants to pick up from
here, he's welcome.
