Found a different case where aptitude segfaults, this time I marked a few
packages as auto-installed, and after holding the up arrow for a few
seconds, aptitude segfaulted. A backtrace from this is below:
Program received signal SIGSEGV, Segmentation fault.

Don't send me files in proprietary formats (.doc(x), .xls, .ppt etc.). It
isn't good enough for Tim Berners-Lee
<http://opendotdotdot.blogspot.com/2010/04/rms-and-tim-berners-lee-separated-at.html>,
and it isn't good enough for me either. For more information visit

Truly great madness cannot be achieved without significant intelligence.
 - Henrik Tikkanen

If you're not messing with your sanity, you're not having fun.
 - James Tocknell

In theory, there is no difference between theory and practice; In practice,
there is.
