That thread 14 must be from a different crash log, the names of the threads do not match, but never mind.
The first part you posted looks suspiciously like the problem many posters had, when Aperture 3.4. first has been released. Did you upgrade to Aperture 3.4. from an early Aperture 3 version?
Then you need to reinstall from your original installation media, see:

You are welcome. I am glad it worked for you.
My suspicion is, that you upgraded from an Aperture version that uses an incompatible "Account Configuration Plug-in", and when Aperture tries to set up Facebook account data, Aperture crashes. Reinstalling from an earlier version or completely new installs the correct plug-in, a similar crash is here:
@ Aye Es Oh : This is probably another case like the one you mentioned in your earlier post! It is still going on. I hoped the 3.4.2 release would fix this.
