It appears to be memory corruption, so crashes showing up elsewhere is
probably just fallout. I tried running it under valgrind, and thanks
to the extra space it reserves around allocated regions I could now
set the package limit without crashing. It also resulted in a logfile
full of memory access errors. I don't know anything about the
structure of aptitude or cwidget but this may be something to look at.

(I'd never used valgrind before but it turned out to be a simple
matter of "valgrind aptitude 2>logfile")
