🤷🏽‍♂️ Current Behaviour

The error below happens when I try to run PB for Desktop.

[pioneer@hydrargyrum-vm-manjaro PB for Desktop]$ ./pb-for-desktop
A JavaScript error occurred in the main process
Uncaught Exception:

🎯 Expected Behaviour

The app should run without an error.

👟 Steps to Reproduce (S2R)

1. Install the app
2. Run it in the console

🏡 Environmental Context

App Version
v9.5.0
Installation Type
An install from a fixed PKGBUILD, as the one in AUR is outdated.
Operating System
Manjaro Cinnamon

Suggested solution

As a quick workaround, setting the XDG_DATA_DIRS=/usr/local/share/:/usr/share/ to the default value suggested here works for me. I'd suggest adding a check for undefined for the XDG_DATA_DIRSvariable (and maybe some other variables too), in the application.js file, line 85 which raises the exception.

@pioneer Thanks for the report. Please re-test whether this issue still occurs in the new version (10.0.1).
