Wow, that's broken. So debconf reinvokes the maintainer script when the confmodule is sourced and then goes and parses everything on stdout. (Apart from the fact that the postrm is effectivly invoked twice.) The way to write to stdout according to confmodule is to write to fd3. But of course confmodule's presence is not guaranteed and thus one cannot just source it and write to fd3... Thanks a lot for the bug report and for the trace. I'll think about it.
