Comment 6 Renato Botelho do Couto 2011-04-27 13:12:20 UTC
I start having a problem on my RHEL 6 after update tmux to 1.4-3. Let me describe what is happening.

I have 2 shell scripts that that I'll attach to this bug, the purpose of those scripts is to open mutt and irssi inside a renamed term and a tmux session, i use it to have specific rules on my window manager for these terms and use tmux because if I close the window (or Xorg) the sessions remains.

It was working fine until this morning. After upgrade what happens is.

I run the first script (doesn't matter if it's mutt.sh or irssi.sh) and it works fine, when I run the next one it simply doesn't work.

After run it with sh -x, i see it stuck in the command "tmux has-session -t irssi" and never goes on.

If I run the same has-session command on a terminal, it returns fine for me saying there is no session with this name and exit 1 as expected.

Let me know if you need more information about this problem.

BTW, how can I find source rpm of 1.4-2? I tried to find it to compare with 1.4-3 and understand what exactly had been done.
