Description

When I run LC_ALL=C firejail --profile=/etc/firejail/element-desktop.profile /usr/bin/element-desktop Element does not launch and this is the output:

Steps to Reproduce

Steps to reproduce the behavior

Run in bash LC_ALL=C firejail --profile=/etc/firejail/element-desktop.profile /opt/Element/element-desktop (or command above) on Debian 13
It doesn't launch: see console output.

Expected behavior

It should launch.

Actual behavior

It does not launch.

Behavior without a profile

It launches.

Additional context

I renamed the element-desktop.local file to have an empty local config. Should there be some config and if so what should it be? I think the profiles come with firejail.

Environment

Name/version/arch of the Linux kernel (uname -srm): Linux 6.12.74+deb13+1-amd64 x86_64
Name/version of the Linux distribution (e.g. "Ubuntu 20.04" or "Arch Linux"): Debian 13
Name/version of the relevant program(s)/package(s) (e.g. "firefox 134.0-1,
mesa 1:24.3.3-2"): 1.12.13
Version of Firejail (firejail --version): 0.9.74
If you use a development version of firejail, also the commit from which it
was compiled (git rev-parse HEAD):

Checklist

I am using firejail 0.9.80 or later
I am using the full program path (e.g. firejail /usr/bin/vlc instead of firejail vlc; see https://github.com/netblue30/firejail/issues/2877)
The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
I can reproduce the issue without custom modifications (e.g. globals.local).
The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
The profile (and redirect profile if exists) hasn't already been fixed upstream.
I have performed a short search for similar issues (to avoid opening a duplicate).
- I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)
