Is anyone in "Stable" going to revert to the older, working, version? 
Were there specific security fixes in this newer version you are attempting to keep track of? 

When "long term stable" becomes "crashy" someone may need to rethink the
use of the word "stable" - "Constant ABI" may be the preferable term.
