Good advice, but one caution, Aye Es Oh;
the support article will apply, if you upgrade directly from an AP 3.3 version to 3.4.2, but not for upgrades from 3.4.1.
If the crash happens after upgrading from a working AP 3.4.1 I'd suspect to be more likely that the library needs fixing.

True, I have a feeling that most of the posts are coming from people that don't use Aperture that frequently, or folks that just recently upgraded from Snow Leopard to Mountain Lion.

Looks like the ghost of this issue is still lurking around in 3.4.3. If you're still seeing this after the 3.4.3 upgrade, go ahead and reinstall Aperture, and that should fix this particular crash.
