Error in Babel package (version 0.9.5). I change 'n%10< =4' to 'n%10<=4' in /usr/local/lib/python2.6/dist-packages/Babel-0.9.5-py2.6.egg/babel/messages/plurals.py file (line 180). In trunk version of package this error fixed.

[Denis Konchekov (dkonchekov)]

But why web client uses this package now? It added problems to everyone who don't use trunk versions of all python packages.

[Peter Glock (peter-glock)]

just to confirm, fixing the simple typo in plurals.py allows the web client to start.

Unable to start web-client after latest update revision 4137.

> But why web client uses this package now?

The web client has been using babel for months if not years, the issue arose because serbian translation files were generated (and parsed), and the bug is specifically in the serbian pluralization support. Since translations in the web client didn't work until last week, this issue went under the radar until I "fixed" it.

[Xavier (Open ERP) (xmo-deactivatedaccount)]

Should be fixed, users of serbian translations will have to either roll back Babel to 0.9.4 or use the Trunk version, but apart from that things should now work correctly for the other locales.

[Peter Glock (peter-glock)]

Fixed for me. Thank you.
