Original GitHub issue: https://github.com/netblue30/firejail/issues/556

Was told to report this issue from distro downstream from Debian Jessie (jessie-backports).

Firejail whitelisting fails because /etc/skel/.bashrc is a symlink in their distro:

user@host:~$ firejail /usr/bin/iceweasel
Reading profile /home/user/.config/firejail/iceweasel.profile
Reading profile /etc/firejail/disable-mgmt.inc
Reading profile /etc/firejail/disable-secret.inc
Reading profile /etc/firejail/disable-common.inc
Reading profile /etc/firejail/disable-devel.inc
Reading profile /etc/firejail/whitelist-common.inc
Parent pid 30345, child pid 30346
Error: invalid /etc/skel/.bashrc file
Error: cannot establish communication with the parent, exiting...

Issue goes away when /etc/skel/.bashrc is not a symlink (rm -f /etc/skel/.bashrc and copy original instead)

I can't check if fixed in 9.40 or not, sorry, but not finding tickets.

How to reproduce:

cp /etc/skel/.bashrc /etc/skel/.bashrc.orig
rm /etc/skel/.bashrc
ln -s /etc/skel/.bashrc.orig /etc/skel/.bashrc
firejail /usr/bin/iceweasel

Also happens on 9.40 (attempted on another distro).
