I have 0.2.0-2 working on my side but I think I had to downgrade some of the pyside library.
basically, I have removed python-pyside* and installed alarmed again (from extra-testing). But if you removed alarmed, and do an apt-get autoremove (or remove, or autoclean, not sure which one is needed as I am just a noob), that should be enough except if you have another application depending on python-pyside !
