virtualbox-ose-dkms package installation leaves a directrory in ~

[Wes Peacock]

If you:
    apt-get install rpm
and then later
    apt-get install virtualbox-ose-dkms
the second install will leave a $HOME/.rpmdb directory

It appears to be a problem in dkms, as the problem evinces after installing bcmwl-kernel-source as well

I've attached a script & log file that shows the bug in a Ubuntu 12.04 Live CD session

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu 12.04 LTS

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
apt-cache policy rpm virtualbox-ose-dkms
rpm:
