[Bug 803369] [NEW] kpackagekit hangs indefinitely when apt-listchanges is supposed to display any changes

[Thilo-Alexander Ginkel]

Public bug reported:

Since upgrading to Natty, kpackagekit hangs indefinitely from time to
time when installing updates. A quick check revealed that it is waiting
for a pager process running in the background, which has been triggered
by apt-listchanges:

root     11617  0.0  0.0   4220   584 pts/3    S+   11:16   0:00 /bin/sh /usr/bin/sensible-pager /tmp/tmp2g9Idx

As it is impossible to interact with that process due to the lack of an
associated console, kpackagekit will just sit arond and wait forever.
