I can reproduce the error in a clean debian/experimental environment
when installing the packages from experimental. Turns out there is a
(subtle) ABI break in libapt-inst, sorry for that. As a workaround,
you could use the libapt-inst1.5 from experimental or wait a little
bit and I will upload a fixed package to experimental.

Cheers,
 Michael
