As the titles says, please report bugs starting with version 0.8 and newer of Liberty.
If possible, we'd appreciate logs to go along with reports. If you don't know how to pull one via adb, download aLogcat from the market.
Please send them to libertydevs [at] gmail and MOST importantly, include the issue in the subject or in the body of the email. I can't tell you how hard it is to dissect a log without knowing what steps were being taken or what is even being reported.
Thanks for continuing to make Liberty a great experience on DX/2 devices.
