Filenames are clipped in progress dialog

[Casey Watson]

The "Creating New Backup" dialog clips the displayed filename that it is currently adding to the archive.

The following is displayed when creating a backup of my Pictures folder:
"Adding file to archive: /home/cwatson/Pict..."

In my humble opinion this dialog should be resizable. This dialog is at this state for quite a while so it is useful to see what files and subfolders it is spending so much time on.

Another potential solution might making the dialog wider and showing the most significant part of the filename. Something like: "Adding file to archive: /home/cwatson/Pictures/.../Wedding/PIC596.JPG". However, I think making the dialog resizable would do the trick.

In general this application is very clean, I am impressed with the direction that you are taking it!
