Octopi shows duplicated packages into group filters

[darkneptune]

I found a rare bug with 'Octopi'. I am an user of GNU Parabola. (where 'octopi' is installed without nonfree pacaur and yaourt recommendation)

Into "show all groups", the two versions of a package like 'kmail' or 'blogilo' are shown right (with a normal version and a nonprism version), but if you apply the filter group like 'kde-applications' the package appears duplicated. !!!
