Okay everyone please try again, I've updated the deb to include a small work around for anyone who was having osso crashing problems. If you had any other strange issues or unexpected things you need to make sure:
1) You uninstall flipclock (latest version, or any version)
2) You manually remove /home/user/.flipclock.conf
3) RE-install the latest deb by following the link on the garage page:
https://garage.maemo.org/frs/downloa....1.5_armel.deb

Lemmy, update to the latest deb following these instructions, then run flipclock from a terminal and let me know what the output is; I've added some extra debugging lines to help try and troubleshoot your wallpaper problem there...
