Comment 5 for bug 451268

Hi,

I'm using backintime-kde4 (version: 0.9.26) on Kubuntu 9.10.

When clicking the "Take Snapshot" button the GUI says "Compare with snapshot ..." forever and nothing happens at all.

When starting backintime-kde4 from terminal, the application shows the following lines when "Take Snapshot" is clicked:

INFO: Lock
INFO: Include folders: ['/home', '/etc', '/root']
INFO: Ignore folders: []
INFO: Last snapshots: {}
INFO: [KDE4Plugin.Systray.run]
INFO: Compare with old snapshot: 20091030-185328
INFO: [KDE4Plugin.Systray.run] begin loop
