But if it were aptitude, I would assume that it would have
a REMOVE line with this package in its logs.

Some aptitude developer told me that installation issues were
in general due to declarations by packages.

I've attached the corresponding part of this file.
Note that libgtk2.0-common is mentioned only at the end
(what I had already given).

It was already available. And I installed it just after the error.
aptitude should obviously have proposed it for upgrade. I don't
know whether this is a bug in aptitude or something wrong in the
dependencies.
