Comment 2 for bug 1027000

A further description of symptoms:

The behaviour seems to be increasingly erratic/unpredictable.

Start a Writer document from and existing file (double click) and the generic LibreOffice icon appears in the launcher with the full white triangle on the left edge and the icon also appears in the alt-tab switcher but neither brings up the document window.

Open Calc document from file (double click) - after first opening Writer - and Calc works fine: a Calc icon appears in both and brings up the document window.

Close both and open Writer document, sometimes it comes up as generic icon sometimes not, sometimes it brings up window and sometimes it doesn't.

There are too many permutations to go through.
