Thank you for that tip. Red pill mode gives more detail as to what's installed; that was a prime reason for temporarily stepping into that mode. When I didn't see Qt anything (or libqt*) I figured something was wrong. Per your note I installed the 4 libqt debs in the dependencies folder and still get the QWidget::repaint recursive repaint warnings and the eventual segment fault.... I even tried a reboot.

I suspect there's some other missing dependency that will show up if / when it becomes one deb package.

Thank you again.
