  I think I need to see what you're doing to see what's wrong.
And more data, e.g., is it crashing immediately or during the download
or at the end?  Does valgrind report anything interesting with the
crash? (although IIRC, valgrind is broken at the moment and prints a lot
of useless false positives)  Is the cache file full loaded and functional
when you try to start the download, etc.

  I think this should work without the ui_download_manager, although
you probably want that too.

  (can't figure out more, may look again in the morning if I have time)
