Comment # 1 on bug 900603 from Dominique Leuenberger

The .pc bump is in sync with also the GI bindings and is there to indicate a
API change.

As you've seen yourself: simply 'detecting' the new .pc file is not always
enough. Some code changes might as well be in order. As a result: nothing wrong
done in Vte: the .pc changed version and the code needs to be updated
accordingly.

=> no GNOME bug, but a QEmu bug.
