--- Comment #6 from Albert Astals Cid <aacid at kde.org> ---
Well, by reading the backtraces it seems you ended up in the

    if ( request->asynchronous() && hasFeature( Threaded ) )
    {
        if ( d->textPageGenerationThread()->isFinished() &&
!canGenerateTextPage() )
        {
            // It can happen that the text generation has already finished but
            // mTextPageReady is still false because textpageGenerationFinished
            // didn't have time to run, if so queue ourselves
            QTimer::singleShot(0, this, [this, request] {
generatePixmap(request); });



situation but it never gets out of it.

Figure out why that happens
