- What I was doing when the application crashed:

Every time you install software crashes after installation

Comment 5 Harald Sitter 2014-01-13 15:35:11 UTC 
Git commit a35ec4bb1019010b0a09fccaec016228813a8e28 by Harald Sitter.
Committed on 13/01/2014 at 15:35.
Pushed by sitter into branch '2.1'.

Prevent nullptr access in Application::name

This is in line with untranslatedName which will only try to fetch the
name from the package object if there is one. ::package() is meant to
'savely' construct one on the fly in case the fromFile constructor was
used.
FIXED-IN: 2.1.3
