Custom action from toolbar doesn't work with parameters

Steps to reproduce:

1. Create the test script:

#!/bin/sh
notify-send "Parameters:" "'$*'"

2. Set it as Custom Action with parameter %f or %F.
3. Put the action on the toolbar.
4. Select some file(s) and click the toolbar icon.

I expect the action applied to selected file(s). The action command runs with the current folder as the only parameter.
