Comment 12 for bug 746694

Interesting... The problem does not occur on my 64bit machine, only on the 32bit.

The update on the 64bit machine did not show as being from Backports on the Udate Manager as it does on the 32bit machines. Remove Backports on the 64bit machine and the 2.30.5-0ubuntu4.1+langfixes~maverick1 still shows (under Security). Installed w/o issue. On the 32bit machines the issue from my comment #11 remains & had to use 'dpkg-reconfigure -a' to get all working again as 'dpkg-reconfigure locale' did not stick on logout/reboot.
