Arch Linux

Description:
firejail 0.9.46-1 causes firefox and thunderbird to crash when launched in sandbox with the standard profiles.

It seems to be an IPC issue and can be fixed for now by disabeling ipc-namespace in /etc/firejail/firefox.profile
For infos see: https://bbs.archlinux.org/viewtopic.php?id=226347

Additional info:
* package version(s)
firejail 0.9.46-1
firefox 53.0.2-1
thunderbird 52.1.1-1

* config and/or log files etc.
(firefox:7): Gdk-ERROR **: The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
(Details: serial 327 error_code 2 request_code 130 (unknown) minor_code 3)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
