Thanks for the update!

Upgraded through the status area applet & HAM.
After the reboot decided to check if all packages were updated by running apt-get update and apt-get upgrade in terminal. To my surprise there were serveral packages to upgrade - it seemed that pulseaudio and qt4 packages were not up-to-date. So I upgraded these also and everything seems to be OK.
So - if you have ringtone problems - maybe it is good idea to check if all packages from the latest update got installed...
