Debconf problem: Question asked twice
there's again something I couldn't figure out in the documentation, and
my knowledge of C is to poor to understand dpkg's or dpkg-deb's
sourcecode. I have tried a patch to tetex-bin's configure script (see at
the end). The patch does what it's supposed to do (see #208408 if
interested). But the question I fiddled with is asked twice: Once when I
expect it, after the line
Unpacking tetex-bin (from tetex-bin_2.0.2-4.3_i386.deb) ...
has been displayed, together with all other debconf questions. Then
comes "Setting up..." of an other package, and then it is shown a second
time when the line
Setting up tetex-bin (2.0.2-4.3) ...
is displayed. To be exactly, just before that, and it's before the
postinst is called (because redirected postinst output doesn't get
spoiled by dialog). I made sure that the seen flag is true after the
first time. Also, the answers I made are remembered. So how come that it
is asked the second time? BTW I do this in a pbuilder-sid-environment,
but the package was build on my working machine which is mixed
woody-bunk1 with a lot of own backports.
I would be grateful for any hints.
