OK, that's really interesting. Thanks.

Well, I am doing it in the postrm, but I should also have mentioned in
the mail that this also happens if I execute the command on the commandline.
I just don't know how remove the diversion now on my system!

So, should I create an extra directory (what? /usr/lib/debug/?)
that contains the debug libs and put that lib above /usr/lib in
the /etc/ld.so.config file?

BTW, as both David Engel and someone else prefered the debug .so
files to be in a seperate package (.dbg?), I guess I'll do that.
But the above problems still remain.
