Lokalize doesn’t have locale-aware formatting (i.e., there is *no* formatting) of the numbers on the status bar. For example, the number 239097 is displayed as ‘239097’ instead of ‘239,097’ (for an en-US locale) or ‘239 097’ (for a nn-NO locale). I’ll try to supply a patch. (This bug is somewhat related to bug #167915. Before the port to Frameworks 5, there was *some* formatting. Now there is none.)
