Crash from boost::condition_variable assert fail when datadir is not full path

Seems datadir can only be a full path, otherwise Drizzle fall down, go boom:

This could be because you hit a bug. It is also possible that this binary
 or one of the libraries it was linked against is corrupt, improperly built,
 or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

read_buffer_size=131072
max_used_connections=0
connection_count=0
It is possible that drizzled could use up to
(read_buffer_size + sort_buffer_size)*thread_count
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
