password gorilla fails to save database on fresh ubuntu 17.10

On saving the password database after adding a new login,
tcl/tk tries to access /sbin/ifconfig and fails as this binary is not available.
Saving without adding a new login is working.

After installing the package net-tools everythings is working fine again.
