I've been working this the past fews days and no progress. The application
locks up to the point I get a Force quit or wait dialog. It seems to be locked
in the file reading part.
The first header and part of a file makes it out, but it locks up exactly 80k
into the first file... every time. The proxy eventually times out and sends
what it has. I think this is a bug in Qt.
When I pause it when it is dead locked, I get:

I would appreciate any tips on how to debug this. Qt 5.4.0
