Comment 14 for bug 1304403

I uploaded a workaround with a transitional package. I also looked into what went wrong in the resolver. Here is what happend:
- pkgDistUpgrade goes over the installed package and mark them all for upgrade
- pkg libkadm5srv-mit9 gets installed as a dependency of krb5-multidev and causes the removal of libkadm5srv-mit8
- pkgDistUpgrade arrives at libkadm5srv-mit8 and marks it for upgrade which causes a MarkKeep() because there is no upradable version

The last step is wrong in libapt, I will look into creating a testcase/fix for this.
