Audacity import dialog in plasma 5 is unpredictably blank

Every now and then, more often on first launch, clicking file>import>audio opens a blank window. When this happens one cure is to right-click the candidate audio file for “open with… Audacity”. That loads the file and then most subsequent attempts will work ok.

possibly by the deletion of the unity-gtk-module package (another thread)?

no it ain’t solved, sorry about that, the import dialog window is still upredictably BLANK

…and the only solution then is to right click the mp3 for it to be opened by Audacity. When the dialogue does work, usually on first launch, it may go blank after the first load.
