Hello,

While running latest Fuel 4.1 release (under VirtualBox VM instance) I have spotted a wild bug under PXE Setup menu option. Sometimes, after triggering the "Check" action, fuelmenu crashes with the following trace:

 Traceback (most recent call last):

TypeError: object of type 'bool' has no len()

This problem is probably connected to the external library - Scapy (2.0.0.10), which fuelmenu is using. The occurrence of this bug has been also reproduced by my collegue Michal Rostecki.
