I have a problem with the filter field.

My table SEANCE has 61134 lines and a ROW labelled ANNEE_U which contains the years :
(9697,9798,9899,...,0506,0607,0708,0809)
If I select the filter ANNEE_U='9899' the result is OK.
But if I select the filter ANNEE_U='0809' I get all the lines of the table !!!

I don't have the problem with the export function. The filter ANNEE_U='0809' works fine

I am using the 1.5.0 version because of the import bug.

Any idea ?
