Hi Seb,

I'm also seeing problems with shell session evaluation but having
trouble debugging. My current suspicion is that the prompt characters
are the problem here (something which differs between you and Torsten)
Could you try using a prompt that ends in '% '? E.g. on ubuntu at least
I can set the prompt in emacs shell sessions with a line like

PS1='\w % '

in ~/.emacs_bash.

Also, please pull latest git as we have just fixed an unrelated bug in
 shell session-based evaluation.

Dan
