Steps to Reproduce:

2.Input right ip address and wrong initiator name
3.click OK

Actual results:
In order to display login failed information,the window of 'ADD iSCSI STORAGE TARGET' has been expanded,and cannot click cancel or quit button.

Expected results:
The window of 'ADD iSCSI STORAGE TARGET' should not be expanded and the login failed information should be wraped.

Additional info:
As far as I am considered,there should be a fix in pyanaconda/ui/gui/spokes/advstorage/iscsi.py or iscsi.glade, i.e.,
add 
self._loginErrorLabel.set_line_wrap(True)
in iscsi.py,
or add wrap property to _loginErrorLabel in iscsi.glade.
