Description:
Everytime when I start to use the application and want to edit the master slide, libreoffice crashes with the following dialogue in the terminal:

Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.


I use Arch Linux (manjaro) and the libreoffice-fresh Also erst 

Steps to Reproduce:
1. Open Impress
2. Choose the master slides Tab on the right panel
3. right click on the actual master slide
4. Choose: Edit Master Slide
5. Crash

Actual Results:  
A tiny window with LibreOffice as title and just an OK as button appears. After clicking the OK button libreoffice crashes.
On the terminal (in case you start libreoffice impress via a terminal just with the command libreoffice --impress) you get the dialouge:

Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.



Expected Results:
Normally I expect that the master slide editor appears to edit the master slide


Reproducible: Always

User Profile Reset: No

Additional Info:
I use manjaro with XFCE
