try and remove qtirreco using appmaneger and all other apps using ir then reboot.,
open xterminal as root write apt-get remove --purge lirc
reboot again download shutter and try if its working now, if its working now download qtirreco and try it. if its still not working try to download another remote. i found that the remote i downloaded to my tv didnt work at all but when i loaded the remote to my digital box it worked just fine.
i think that some of the remotes in the download section dosent work exemple my remote thompson mb-100!
i hope this helps
