(not the maintainer, I don't even have aptitude installled and have no
idea what 'New Categorical Browser' means at the moment but still)

Can you please run 'bt' (backtrace) in gdb as a strcmp call could (and
is) everywhere in aptitude or deeper down in the stack.

Does this happen 'for a while' now or did you find out about it only
recently? Maybe only since an upgrade of x, y and z?

That could be highly state dependent (especially if it isn't aptitude
but libapt failing here) so I wanted to chirp in before this state is
"lost" to an update/upgrade or something.

Maybe make a backup of /var/lib/apt/ and /var/lib/dpkg/status somewhere,
in case we find out the relevant state is dependent on those.

btw: Is cubietruck 'armhf' or 'armel'?
