ok, so i see what the problem is... in systemimpl.cpp SystemImpl::createEnt=
ry=20
there is this:

    if (!empty_icon.isEmpty())
    {
        KURL url =3D desktop.readURL();

        m_lastListingEmpty =3D true;

        KIO::ListJob *job =3D KIO::listDir(url, false, false);
        connect( job, SIGNAL( entries(KIO::Job *,
                              const KIO::UDSEntryList &) ),
                 this, SLOT( slotEntries(KIO::Job *,
                         const KIO::UDSEntryList &) ) );
        connect( job, SIGNAL( result(KIO::Job *) ),
                 this, SLOT( slotResult(KIO::Job *) ) );
        qApp->eventLoop()->enterLoop();

        if (m_lastListingEmpty) icon =3D empty_icon;
    }

if i #ifdef 0 out that loop system:/ lists instantly

for whatever reason, trash:/ is painfully slow on my system here (haven't=20
investigated the cause of this yet). so getting the listing for trash:/ slo=
ws=20
system:/ down dramatically, and since it's done syncronously the listing ju=
st=20
apears to "hang". i imagine this will be true of any service that takes a=20
while to load and has an empty icon.

it would be nice if this could be done async... i looked at the code and it=
=20
would be doable from within kio_system (i've made the job processing async,=
=20
even =3D) if there was only a way to update an entry from an ioslave that's=
=20
already been passed to listEntry(). i'm sure there is, i just don't know=20
how ...
