Description

Skype crashes when sharing a file

Steps to Reproduce

Steps to reproduce the behavior

Run in bash LC_ALL=C firejail skypeforlinux
Try to share any file in a chat.

Expected behavior

File should be sent to the buddy without any issues in the client.

Actual behavior

The whole Skype window freeze and must terminate it from the terminal.

Behavior without a profile

File sharing works fine but keyboard typing doesn't work.

Additional context

None.

Environment

Ubuntu 22.04.
Firejail version (0.9.70).

Checklist

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)
