a shot in the dark to work-around windows file-import limit.

When importing to new tracks, newly created tracks are selected

Editor::track_selection_changed()
-> SoundFileOmega::reset()
-> SoundFileOmega::reset_options()
-> check_info() fails ->  Glib::signal_idle() error message.

it is unclear why check_info would fail in this case since it
worked in the first place..  best guess: a concurrency issue
opening the file.
