The minute I enter a command in a terminal, I get the following error when I enter exit (there is no error if I exit right after creating the tab):

During handling of the above exception, another exception occurred:

Thanks a lot for reporting this bug, @davidbrochart!

I'll try to fix this asap. What operating system are you using?

It's an old RedHat Entreprise Linux 5.7.

I have upgrated pymux and I have noticed that there is some improvement but now sometimes when I exit pymux freezes. Here is the stack trace:

Hi @davidbrochart, Thanks for this traceback!
I added a try/catch around this tcgetpgrp call: 77463d8

I'm not sure why it happens, maybe some timing issues. (It could be that the process group is not around when the process terminates, not sure.) But this should probably do it.

Thanks, I will try it out.
