I have mutt set to show my inbox by default, with collapsed threads ("set sort=threads" and "folder-hook '.' 'push <collapse-all>").
When I start mutt from the command line, all is fine - threads are collapsed. However, when I start it as a command to run as an argument to some terminal emulators, all is not fine... With both Terminator and Konsole, I start with 'terminator -e mutt' or 'konsole -e mutt'. The respective terminal window pops up with mutt in it - however, the threads are all expanded. Both Xterm and Terminal, however, don't display this behaviour, they are both fine, ie. threads are collapsed. Using mutt 1.5.20. -- .
