I've given this a lot of though so bear with me. I'm a native Portuguese speaker, our dates are in the format of dd/mm/yyyy, our time format is HH24:MM:SS, etc. but I like keeping my system in English because when an error occurs, it's a lot easier to search for a bug report or a mailing-list message describing a similar problem.
Unfortunately, without some tweaking to system configuration files, it's impossible to configure a system that uses English GUI strings and the rest in native format. For example, in <cof>Windows</cof> I understand it's possible to change date formats, number formats, etc. independently of whatever language the system is. A good example of this is that in my workplace all our Windows boxes have the English version but all formats are local.
I've cooked up a PyGTK application, awfully similar to gnome-language-selector as you'll certainly notice, available here (http://yimports.com/~cpinto/darcsweb.cgi?r=gnome-regional-settings;a=summary) to make those changes but I feel that it would be a lot better if gnome-language-selector actually did this.
Would you care to include a tab in the notebook for users to change the data formats? Maybe an "Advanced" button that pops up a dialog with these settings? For native English speakers maybe this isn't such a deal, but for us technical non-English speaking folks, it makes quite a difference.
I know that this is a feature request but it would be great to still have it included in Dapper.
Thanks for your bugreport.
Sorry for the late answer. It is unfortunately too late for dapper but I would like to see it for edgy. Fell free to merge from my bzr tree (http://
