Cannot add new category in Bees blog module

[hedgehog]

Whenever I try to add a new category in blog module, I got 500 error. Server logs show the following error:

When I put gasoline in my car, it doesn't work... But if I put it in another car, this one works well ! What to think about ? :-)))

@pilou think about you should not put gasoline into a diesel car. Unfortunately, both of my cars are gasoline-powered and the same brand
