I am having a problem where if I go into setting > sound > phone ringtone or notification ringtone then com.android.settings crashes. I can still set the ringtone from other apps but not the notification tone as I dont know of any other way of doing it. I am using this rom on my X10 mini pro.
Any help would be great. I cant post on that XDA thread as I cant get my account to post at all let alone in a dev section.
Some forums have some old "cold war" feelings from the old days. You won't find them here!
I'm going to guess, based on what you say, that the problem is with the Rom. If this happened after you flashed it, I would say it is a bad Rom. This is because you go into the ringtone section, and immidiately it crashes, before selecting an audio file.
If it happened a few weeks or months after you flashed it, then I would say re-flash the rom
I'm not familiar with your phone, so I don;t know what other roms are available.
