Bug report #9742
2.3 files not backwards compatible with 2.2 (Oracle layers)

I have a qgs file created with master (3b4edb8). It contains a raster, couple of shapefiles and several Oracle layers.
When I try and open it in 2.2.0, I get the "Handle bad layers" dialog.
Surely the file should be backwards compatible? It works fine in master and it's only a couple of weeks since 2.2.0 came out.

Ah, I think I see what the problem is.
For some reason installing 2.3 (from the weeklies) has made 2.2 unable to find the Oracle Provider.
That's why QGIS isn't able to open those files - because there is no Oracle provider available.
So assuming that's the cause, the bug is that the handler is appearing when really there should be an error telling the user that the Oracle provider needs installing (on that front, probably relate it to #9636).
