Description of problem:

Code error occurs when attempting to restore archive from ssh2 source.

Version-Release number of selected component (if applicable):

1.43.2-2.fc9

How reproducible:

Every time.

Steps to Reproduce:
1. Create an archive on ssh2 destination
2. Choose to Restore Set
3. Select ssh2 source type
4. Enter all details
5. Click on Test Settings
  
Actual results:

Error dialog window opens with the following message:

Traceback (most recent call last):
  File "/usr/share/fwbackups/fwbackups-runapp.pyw", line 1614, in on_restore1TestSettingsButton_clicked
    if not (host and username and port and folder):
NameError: global name 'folder' is not defined


Expected results:

Testing the restore archive parameters should succeed.

Additional info:

If I skip the Test Settings and proceed with restore the operation will fail nonetheless with the following log messages:

Mar 06 13:09:07 :: DEBUG : Receiving files from server via SFTP
Mar 06 13:09:07 :: DEBUG : Could not receive file from server: Failure
Mar 06 13:09:07 :: ERROR : Source `' is not an archive!
Mar 06 13:09:07 :: DEBUG : Thread returned with retval False

And one usability note. If I click on existing Backup Set and then I choose restore, I would expect the restore mode to be the one from the Backup Set I have selected. A bit boring to have to enter ssh2 parameters with every restore job.
