Previous Report]

• • loss of data last week due to the migration to Phoenix.

 "There are several reasons why we get bad stack traces on
 android, one is that there are no debug symbols for the system libraries (frame
 1), and that leads to confusion in other frames as well. There is some discussion in 
 bug 662936 and its dependencies." - <azakai>
