1. Thank you for deleting the duplicate. I thought my first e-mail
didn't make it.

2. I also used "src/emacs-24.4.1 -Q" or
"src/emacs-24.4.1 -Q -nw", which makes no difference for this problem.

3. However, I get the buggy behavior only on
"SUSE Linux Enterprise Server"  version 10 and 11 (sles10, sles11).
Today I compiled emacs on a "Debian testing" system, where I do
not see the problem.

4. While trying more, I noticed that this is actually not a problem
specific to the shell-mode. It similarly happens in fundamental mode
(but again only on SUSE). So if I type in an empty buffer in
"Fundamental" mode:
1<return>2<return>3<return>4<return>

... I end up with this:
(4 spaces)1
(1 tab)2
(1 tab,4 spaces)3
(2 tabs)4

5. Can someone suggest how to debug this further or find a local fix?

With best regards, Daniel
