Nautilus cannot display multiple python scripted columns

[over 5000]

Binary package hint: nautilus

In the course of bug #228987, I tried to add python scripted columns to nautilus. (Displaying different EXIF data)

Adding several columns does not work. The second one overwrites the first one when adding itself.

None of the columns is shown when their tickmark is ticked.
If one of the tickmarks is ticked then, after closing and reopening the columns window, suddenly both are ticked.

I'll attach the scripts below to make sure there's no bug in the scripts.

Thanks for your comments. This does not appear to be a bug report as such. We appreciate the difficulties you are facing, but it would make more sense to raise your question in the support tracker. http://launchpad.net/support

you should better take those programming questions to the upstream list or in the answers launchpad section

No, honestly I DO believe that this is a bug in nautilus.

I asked Question #36032.

[Sebastien Bacher (seb128)]

could be a bug in nautilus but upstream would be better placed to judge if that's due to your code or nautilus, could you mail their list of use bugzilla.gnome.org?

I doubt this is bug

such behaviour is caused by the same class name on your python modules
class ColumnExtension(nautilus.ColumnProvider, nautilus.InfoProvider)

the author should give different class names on each module and the defect will not happen
