I'm Using Kubuntu 11.10 had used the Kdenlive Add-On Installer to install four YouTube profiles. Initially these did not work due to a missing library libav-extra which I installed. I then reran the config wizard.
Previously before rerunning the wizard, the profiles had appeared in render, although they hadbeen shown as unavailable due to the missing library. Now they no longer appear.
If I go into the Add-On installer, the profiles show as installed. If I click on Uninstall, the button changes to Install Again whic suggests that the profile has been removed, except the XML config files remain in /.kde/share/apps/kdenlive/export/. If I close kdenlive and reopen the add-on installer the profiles reappear as installed. Deleting the XML files makes no difference.
It would appear that the Uninstall process is broken
