There's a file called :.1.gz in /usr/man (being part of the bash2 package).
However, if you try something like this on that file:

zcat :.1.gz |nroff -man

You get an error:

realpath on `man1/builtins2.1' failed: No such file or directory

This is because this file is now called builtins2.1.gz (as all man pages
are compressed now). This is caused by the following line in :.1.gz:

.so man1/builtins2.1

so, probably unzip builtins2 or make : a link to that file ...


This posting goes to you as your package was one of the first ones I found
... a quick check (which might be wrong, but I found that it was always
true for those files I examined manually) showed 750 buggy files.

I used a simple script that I did execute in every directory (there might
be more simple methods, but it happened that I needed something like this
by accident):

for i in *.gz ; do
   zcat $i | man2html 2>/dev/null | \
   grep "^<H1>.*</H1>$"
done | grep "Invalid Manpage" | wc -l

COULD SOMEBODY CHECK THIS???

I think this is a _very_ bad thing. The bug is not big enough to update
every single package, but if you sum this up, it's quite a big mistake ...
(anyway, there are some packages - like bash2 - where this .so syntax is
used in quite a few files. So, maybe change those ...
