pidgin-microblog and pidgin-mbpurple appear to be the same project in two packages

[Scott Ritchie]

Even weirder, they seem to have the same version.

Karmic doesn't have pidgin-microblog but it does have pidgin-mbpurple.
Checking debian Unstable it seems that the opposite is the case -
there's a pidgin-microblog but no pidgin-mbpurple.

They both have different original maintainers, and pidgin-microblog has
a -ubuntu suffix.

It seems like we should standardize on one (and provide a
replace/provides for the other), but I haven't looked at the individual
packaging yet.

Thanks,
Scott Ritchie
