I've been using this plugin for a long time and this is the first time
it has threatened to remove basesystem. So I'd like to understand what
triggered it this time. So much easier to make effective bug reports
if one understands the problem.

A bug in the remove-with-leaves plugin that erroneously tags packages
for removal causes a segmentation fault in PackageKit? Perhaps, but
I'm unconvinced. (And I realize that it is not your job to convince
me...)

Anyway, the "solution" (bug 503989) is, in my opinion, spectacularly
backwards. PackageKit is broken when using the remove-with-leaves
plugin, so disallow using that plugin with PackageKit. This assures
that the bug will never get fixed. If the plugin is buggy and somehow
gets fixed then PackageKit still won't use it, so nobody will know.
If, on the other hand, PackageKit is buggy then it certainly won't get
fixed because the symptom will never be seen now that the trigger is
removed.

In any case, we might as well just remove the plugin completely from
Fedora and call it a day. If another packages has a problem and the
plugin is involved then the plugin is blacklisted. If a user has a
problem and the plugin is involved then the user is instructed to
remove the plugin. At that point, shouldn't we ask why we are shipping
the plugin at all?
