Comment 4 for bug 663925

I have no idea why it is questioned whether this is a valid a bug or not...‽ The webpage clearly confirms the bug, users do not get any warning that they shouldn't set the option allow_physical_directory_deletion to yes (we can't expect users to go to the project's webpage after installing a package) and the bug "has a severe impact on a small portion of Ubuntu users" (i.e. fulfilling the criteria for importance "High").
