Still doesn't help :-(. Maybe I am doing something wrong...I don't know if 
I can "debug" this query on a lower level...

This works for me correctly:

ogrinfo -where "KOORDINATAX=5460870" krk.ovf krk

although I get :

ERROR 4: Update access not supported for VRT datasources
Had to open data source read-only.
