(Ubuntu mostly uses automatically-rebuilt debian packages, so debian
bugs become bugs in ubuntu too)

No; at least I don't think so.

ah, ok. For the beta of the OSGeo live-dvd I have xUbuntu 9.10 on a
bootable USB stick so I can test. Yes, I get the same problem.


I notice in the main layer manager window "Command output" tab is this
error:

This is with version 6.4.0~rc5-3~karmic1 from UbuntuGIS's launchpad.ppa
repository. Are you using the same?


basically 6.4.0rc5 is about 6 months old now and this is almost certainly
already fixed since then. the fix is going to be us releasing 6.4.0rc6,
and then the various distro teams packaging that. I don't know when that
will be, but I can only say that we are making good progress right now
and I hope it will happen very soon.

that's essentially what the existing menu item does. (or is supposed to
be doing)

fair enough.
