as result in Yast GUI all settings for bridge device are missing and device type is shown as "ACRnet" type device with name "bridge".

Problem affects yast only, after manual configuration editing system runs as expect.

Reproducible: Always

Steps to Reproduce:
1a. create bridge device configuration in /etc/sysconfig/network 
or
1b. create bridge via yast - Network Devices
2. try to edit this configuration via yast - Network Devices
3. try assign firewall zone in Firewall module

Actual Results:  
any exiting bridge device configuration 
a) can't be edited via yast
b) crashes firewall module


looks like source of problem is Ryby module: modules/NetworkInterfaces.rb
