Subject: Log tracepath for stack validate exceptions.
X-Git-Tag: 2014.1~735^2

Log tracepath for stack validate exceptions.

Calling validate on each resource exercises a lot of code, and
will at times cause non-validation related exceptions.

This change just logs the tracepath for any exception that happens
during validate.

This may be a contender for backporting to milestone-proposed,
since diagnosing some problems on the grizzly branch will be
difficult without it
