When i run it for the first time it returns: Traceback (most recent call last): File "/usr/share/fwbackups/fwbackups-runapp.pyw", line 2602, in <module> MainApp = fwbackupsApp(verbose, minimized) File "/usr/share/fwbackups/fwbackups-runapp.pyw", line 122, in __init__ self.runSetup(minimized=minimized) File "/usr/share/fwbackups/fwbackups-runapp.pyw", line 354, in runSetup 'has been created in /etc/crontab.fwbak' % error) TypeError: not all arguments converted during string formatting so i touch /etc/crontab (it doesn't exist on archlinux) and now it works.
Fixed locally in git, the problem will be fixed in 1.43.3rc2 (which is set to be released relatively soon).
