[Teamspeak 3] the application crashes on opening the options window

[ghost]

I just tried to use the official profile bundled with firejail, only to discover that it causes the application to crash on opening the options window after joining a channel on a voice server.

It does not crash as long as you're not connected to a server; otherwise, Teamspeak will crash on every attempt to open settings if you connected to any server at least once - it's persistent between restarts of the application.

tl;dr 1.Run Teamspeak and join a voice channel on a server; 2.Try to open the options window; crash 3.Run Teamspeak again and do not connect to a server; 4.Try to open the options window; crash

Also: 1.Run Teamspeak without firejail and close it; 2.Run Teamspeak with firejail enabled now; 3.Try to open the options window; it works again 'till you connect to a server and join a channel

Hi @Hasbreak, does it work when you start it with firejail --protocol=unix,inet,inet6,netlink teamspeak3?

[ghost]

Hi @smitsohu. Yes, it does work just fine when started using that command (absolutely no crashes when opening the options window under any of circumstances I specified above). However, there's one more lookout to be addressed as Teamspeak doesn't start with /usr/bin/openssl blacklisted by default.

/usr/bin/teamspeak3: line 19: /usr/bin/openssl: Permission denied
Could not find CA certificates location

noblacklist /usr/bin/openssl in /etc/firejail/teamspeak3.local does the job.

@Hasbreak Can you try out 96f26b0cec577006917e4385511bf7cf81d6421c and see if it works?

[ghost]

@Fred-Barclay I made the following changes to teamspeak3.profile and none of reported issues is present. It's all fixed. 👍

[Fred-Barclay]

That's great! Thanks @Hasbreak and @smitsohu 👍
