Regarding keeping things in sync: I've prepared a changeset to libtaskmanager that deletes around 90% of stunningly redundant icon code and will replace it with a call to KWindowSystem::icons(). It won't pass the ClassHint flag though to avoid an additional XGetClassHint in KWS since it has the ClassHint already, so it will do the fallback itself.
