The bug is really in the mpm packages, which are allowed (by the package
relationships) to be unpacked before apache2-common's removal, thus breaking
apache2-common's prerm script due to the ABI mismatch.

I think a Pre-Depends on apache2.2-common is going to be needed here to
preserve the necessary unpack order.  In any event, it can't be fixed in
apache2-common, since that's the package that's been removed. :)
