Nautilus not garbage collected ?

Hi,

Yesterday I needed to browse the instances of
FTPluggableIconListMorphAdaptor and I saw that I had 117 of these.
So I browsed the instances of Nautilus and I saw I had a lot with no
window open.

On a new image I ran:

10 timesRepeat: [
|nautilus|
nautilus := Object browse.
nautilus close.
].

Then print:

10 timesRepeat: [ Smalltalk garbageCollect ].
Nautilus allInstances size.

I get 10.

If I launch the same in Pharo 4 (just replacing Nautilus by
PackageTreeNautilus) I get 0.

I checked the class that points Nautilus instances:

(Nautilus allInstances flatCollectAsSet: #pointersTo) collect: #class.

And I saw that QANautilusPlugin points to them.
If I disable QANautilusPlugin the new instances of Nautilus are garbage
collected.

I am not sure but I think this comes from the SystemAnnoucement.

Should I open a bug entry ?

Thanks Cyril. This is already solved in the upcoming version of quality assistant. But maybe we can add a test case like that, so in the future this will not repeat?
