  thanks, but now it doesn't work at all, I can't see similar bug
report:

jojda:/home/erik# time aptitude 
Ouch!  Got SIGABRT, dying..
Aborted

real    0m19.414s
user    0m19.130s
sys     0m0.040s

  when it starts it displays the message "Loading cache", stays like
that for 19.414s and quits with the above message (same when run without
timing it)

  strace reveals:

write(2, "aptitude: pkg_grouppolicy.cc:779"..., 146aptitude:
pkg_grouppolicy.cc:779: void pkg_grouppolicy_task::add_package(const
pkgCache::PkgIterator &, pkg_subtree *): Assertion `tasks' failed.
) = 146

  this message is never seen, even though it looks like it should go to
stderr, maybe it's redirected somewhere...

  here's the end of strace:

  looks like bug, doesn't it? but considering that I didn't update
aptitude in few days (since nov 22) I guess it would already show up in
bug database...

  ideas/comments appreciated... TIA
