Public bug reported:
After selecting all available updates (key "U"), on the confirmation
screen (key "g"), after highlighting a package (up/down arrow keys) and
asking for the changelog (key "C"), the changelog is downloaded and
displayed, except a red background warning is shown that after dropping
privileges (changing to user _apt) the program encountered a Permission
denied error. Logging in on another virtual console and listing /tmp
shows that the directory aptitude<random> is owned by root, group root,
with "rwx" for the owner and no other mode bits set. Ergo when a
process sets its UID to the one for _apt (118), no operations will be
possible inside that directory.
