#251: apt fails upgrading or removing python package

Priority:  major   |   Component:  Package
 Version:          |    Keywords:  pkg-apt
-------------------+--------------------------------------------------------
 The standalone apt.exe loads the python dll located in the same directory
 as itself even though it has the dll packaged internally. Consequently the
 in-use file cannot be deleted and replaced.

 Workaround: copy apt.exe to a different location and run from there.
