Comment 29 for bug 730476

Ok, in my case it was a different problem. I had configured language support to display numbers and dates in german, with an otherwise english installation. My custom date format included the name of the day. The indicator applet was then using one locale to measure the maximum size of the string, and another to actually render the string.

In the code, measuring is done using the strftime function while the rendering uses g_date_time_format. It seems these two functions use different parts of the locale settings.

I hacked the code to use g_date_time_format in both cases and it is now displaying correctly for me.
