Bug#554460: update-notifier: apt-check hangs using 100% of cpu

[andy]

Package: update-notifier
Version: 0.70.7.debian-7
Severity: normal

hello -

i noticed that apt-check is apparently hanging while using 100% of
the cpu.  attaching to the process using strace shows nothing after
the "Process XXXX attached - interrupt to quit" message.

this is reproducible and affects other accounts on the system.
attempting to run the command manually shows:

% /usr/bin/python /usr/lib/update-notifier/apt-check
/usr/lib/update-notifier/apt-check:62: DeprecationWarning: apt_pkg.GetCache() is deprecated. Please see apt_pkg.Cache() for the replacement.
  cache = apt_pkg.GetCache()

/usr/lib/update-notifier/apt-check:66: DeprecationWarning: apt_pkg.GetDepCache() is deprecated. Please see apt_pkg.DepCache() for the replacement.
  depcache = apt_pkg.GetDepCache(cache)

nothing else is displayed, and at this point attempting to interrupt
the process with ctrl-c fails.

thank you for your time and effort.
