I guess there's not much point, the problem solved/design flaw worked
around by removing plasmoids that are possibly unstable. It does kind of
limit the usefulness of the whole plasma system though - anything which
might possibly hang should not be used. This particular machine is a
netbook so I expect to use it in various places where internet
connectivity is bad or non-existent.

It sucks for the users who don't know how to debug technical problems
and search on mailing lists though - no wonder there's so many posts on
forums about 'KDE freezing' or 'KDE hanging'.
