@smcv: Do you think this is a failure of dpkg/apt cleaning up old
versions? My suspicion is rather, that there is some old copy of libglib
lying around in /lib/x86_64-linux which was copied there by some 3rd
party installer, possibly lying around for years there. It was simply
undetected so far.

@rektide: the time stamp of
/lib/x86_64-linux-gnu/libgobject-2.0.so.0.4200.0 would be interesting.
Does that coincide wit the installation of a proprietary/non-Debian
package or the use of "make install"?

Regards,
Michael
