Value from config profile.snapshots.min_free_space.value not loaded in GUI

Using latest backintime (1.6.1), installed in Arch. - In the GUI, edit profile settings ("Manage profiles") - In the "Remove & Retention" tab, set the value for "...the free space is less than" to e.g. 50GB - Save the profile - In the config file the value for "profileX.snapshots.min_free_space.value" is correctly set to 50 - Restart backintime GUI (Important!) - Open the edit profile dialog again - BUG: The widget for the space now shows "1GB" and not "50GB" (The config file then is still OK, but if you save the dialog, then your initially selected value will be overwritten with 1, unnoticed by yourself)
