[horde] I've got "Aufgaben" instead of "Tasks" on Horde webmail 4.0.8

[D G Teed]

Running Horde webmail 4.0.8.  All portal blocks have english titles
except Aufgaben.  It was like this immediately on install.

Even with my Global Preferences set to English, the title
remains Aufgaben.  This was an upgrade on a copy of the Horde Webmail 1.29
database, but there are no other errors like this.

Everywhere else I look, such as clicking on Aufgaben link, shows
English, such as "My Tasks".

Any one else get this?  What can be done to correct/investigate why...
