When you open LibreOffice Impress by double-clicking the launcher icon or desktop file and then cancel a document recovery, LibreOffice does not open Impress but instead a generic "new document" dialog.
Steps to reproduce:
1. Have a Writer odt file waiting for recovery.
2. Open Impress. The recovery dialog comes up although it is about a Writer file and not related to your Impress work.
3. Cancel the recovery.
A generic "new document" dialog comes up and you have to choose again to open Impress.
It continues opening impress since that is the program that you launched.
Before that it would better not interrupt you for recovery of a Writer file (or at least allow to "skip, not now").
Operating System: Ubuntu
Version: 188.8.131.52 release
I can't reproduce because I don't know how to crash LibreOffice and get the recovery dialog. ;-)
That said, I believe what you describe but it is not really a bug as it works as designed. So set as enhancement.
