skypeforlinux fails to start on Arch Linux

[Kishore96in]

firejail skypeforlinux fails to start on Archlinux unless I add ignore apparmor to my skypeforlinux.local file. apparmor is enabled in this profile by the inclusion of electron.profile.

Reproduce
Steps to reproduce the behavior:

1. Run in bash firejail skypeforlinux

Result
firejail skypeforlinux exits without any obvious error, but does not launch the application. Skype launches normally if I type skypeforlinux or firejail --noprofile skypeforlinux. Skype also launches in firejail if I add ignore apparmor to my skypeforlinux.local file.

Environment

• Linux distribution and version: Arch Linux
• Firejail version: 0.9.64.4

Checklist

• The profile (and redirect profile if exists) hasn't already been fixed upstream.
• The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
• I have performed a short search for similar issues (to avoid opening a duplicate).
• If it is a AppImage, --profile=PROFILENAME is used to set the right profile.
• Used LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8 PROGRAM to get english error-messages.
• I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
