Dear Maintainer,
* What led up to the situation?
When lunching `sqlitebrowser` the windows is not displayed as it should.
* What exactly did you do (or not do) that was effective (or ineffective)?
In a Mate terminal I run:
$ sqlitebrowser
* What was the outcome of this action?

No terminal output and the `sqlitebrowser` window properly displayed.
