That looks like a definite aptitude bug. I don't know if it's causing
your crash, though.
Could you see what happens if you apply the attached patch?
Thanks,
Daniel

Thanks for your help and your patch. This fixes the new / delete
mismatch. Valgrind still complains about two jumps conditional upon
uninitialised values:

By the way, I still get a segfault when not running under valgrind --
but I've now noticed that this is accompanied by various complaints
about "Badness in handle_page_fault at arch/um/kernel/trap_kern.c:98" in
/var/log/messages, so I suspect a User-Mode Linux kernel bug is causing
this rather than aptitude.
