I regret that I don't know how to file a bug report,
hence this email.
This system is Debian Lenny, upgraded about a week
ago (but I do apt-get update almost every day).
I find that kpackage doesn't recognise that iceweasel
has been updated to 3.0.1-1 (from 3.0~rc2-2).
Synaptic knows this fact.
There are several bugs in kpackage.
Sometimes packages vanish from its list.
Usually they reappear on reloading.
Please do something about kpackage.
It is the most convenient package manager,
far better than synaptic in most respects
(or would be if it was bug-free).
With best wishes,
