Note that the 'new' twitter_1.3.95+0m8_armel.deb package would conflict with the installed version of mp-harmattan meta-package (which has a strict dependency to twitter 1.3.50).
As that package is adding nothing to the system, just collecting minimum dependencies level for other twitter packages, I suggest to avoid installing it at all (but the best suggestion IMHO is anyway to wait that official upgrade is out, as I wrote earlier, twitter is known to have tricky regression bugs)
