evolution and default applications for attached files
 

Am using KDE under Debian.

What is it that controls the file associations and default applications that Evolution makes for attached files?

Everything worked fine until a month or so ago, when suddenly (after an apt-get dist-upgrade) attached files have only the "Save as..." button, and not the "Open in openoffice.org Calc..." (for example).

I'm guessing there is some gnome config file somewhere, but darned if I can find it.
