udev mount failure with error code 32

[Ulrich Steffens]

Dear team
when connecting a usb-flash-stick, udev should execute an external bash script containing a mount command to mount the usb stick. The mount fails with error code 32, no further message.

The udev system was running fine as expected in previous versions, e.g. 16.04.

Is this realy a bug ?
