I get a crash in KoFilterChooser, namely here:

54          m_filterList = new QListWidget(page);
55          layout->addWidget(m_filterList);
56          page->setLayout(layout);
57
58          Q_ASSERT(!m_mimeTypes.isEmpty());    <--- this line
59          for (QStringList::ConstIterator it = m_mimeTypes.constBegin();
60                  it != m_mimeTypes.constEnd();
61                  ++it) {

I don't think the problem is in the qpro filter, this is somewhere else.  And 
this is in 2.9.
