I'm 99.99% sure this has nothing to do with aptitude. aptitude doesn't do any of the actual mechanical installation of packages; it just asks libapt to invoke dpkg with appropriate command line arguments.
One thing that could cause this problem would be if that directory already existed on the system with those permissions. For instance, firefox seems to create and populate it if run as root. I'll reassign it there (and bump the severity to "serious" for this FHS violation: "/usr must be sharable and must not be writen to"). Actually, I guess iceweasel is the right place these days?
