Sounds like broken preexec()/precmd() hooks to set terminal titles. If
you didn't write those yourself, I'd suggest you report it to the person
who did.

You can try this to check:

  % unfunction preexec
  % unfunction precmd
  % unset preexec_functions
  % unset precmd_functions

After that, any hook functions should be disabled I think.

I happen to know the grml-setup a fair bit, and I think its title hooks
are fairly solid. If you mess with $TERM however and make the setup
think it is running in a terminal that would support terminal title
setting, although it's actually a terminal that doesn't, then things
like this can happen as well.

If you still think it's a bug, visit the grml folks on IRC:

  #grml on the freenode network

...and tell them, or report a bug via their bug tracking system:
