Since I updated to 1.3.1 something went wrong when searching with date-fields in the userlist.

The search itself gives a good result but after displaying the result the fields in the searchform are reset to random values instead of the search values.
For example:
Searching on registration-date between 2010-1-9 and 2010-1-10 gives a good result but after the search the fields shows 2009-1-20 and 2010-1-20

Searching on an age range between 30 and 50 gives a good result but after the search the fields shows 18 and 18 (in this case the minimum posible value)

This is rather annoying for users because every time they have to re-enter the values when refining the query.

Is it possible to downgrade from 1.3.1 to 1.3.?
Just by putting the expertfiles from 1.3 maybe...??
