HI

I use a KIO::PreviewJob in my app to create preview images. But ever time I make a \
function call on this object my app segfaults

I use the following code:
if(preview_job){
    preview_job->kill();
    preview_job = 0;
}

Using other functions than kill() results in the same problem, too :(

It was working fine for some time and then suddenly it stopped working and is \
crashing all the time.  There are two more parts of my programs which has the preview \
job:

preview_job = KIO::filePreview(KURL::List(item.url()), preview_frame->width() - 10, \
0, 0, 0, TRUE, FALSE, 0); connect(preview_job, SIGNAL(gotPreview(const KFileItem*, \
const QPixmap&)), this, SLOT(slotSetPreview(const KFileItem*, const QPixmap&))); \
connect(preview_job, SIGNAL(result(KIO::Job*)), this, SLOT(slotGotPreview()));

and
preview_job = 0;

If I remove the function call everything works fine besides of some problems of \
previous jobs ending after the current job are overwriting the previews... Thats why \
the old jobs have to be killed :)
