Looking at the code it's not surprising. vfs301 driver just stops after scanning a single image, while libfprint core doesn't expect it. Moreover, this driver doesn't support proper deactivation, i.e. it's not possible to cancel an operation in progress. Unfortunately, I have no vfs301, so someone with device should fix the driver and submit a patch.
