Equipment used :

My computer running on Linux -  Kubuntu 18.04.2 (with KDE)

Minecraft Launcher (official .deb) version 2.1.5410

The bug :

When you want to create/edit a profile, the browse button in the profile settings doesn't work. It simply change color, but it does nothing else (as shown in the screenshot above).

​​

What is expected :

Open the file directory, I guess.

How to reproduce :

• Start the launcher on a computer that runs Kubuntu
• Create a profile
• Try to use the "Browse" button
