According to the message when you log on, PitBull has problems that will be fixed in WoW 2.1.2, however using PitBull-r39408 should resolve it for now.
So far I was unable to trace back the issue to a certain group of add-ons. The AceEvent20Frame reference in the memory dump may or may not be related to the use of the Ace function, however I remember that after the Black Temple patch I had several crashes until a friend of mine told me to download certain fixed Ace2 libraries, which put an end to those crashes.
I'll talk to him later today to figure out what Ace library/file was updated.

By the way, my cache was cleared quite a few times since the first crash occurred, and I even went through the pain of reconfiguring PitBull and other add-ons after nuking the WTF folder.
Now my add-ons are "without externals", and I switched to using the !!StandaloneLibraries package + WhoLib (which is not included): I'm freaking glad because it has already eliminated an infrequent but annoying error (/who spam generated by SpamSentry/Eloquence/Prat combo).
Then again, it'd crash while marking targets too, sometimes while disenchanting.
Anyhow: Fix for me -> Deleted all my SavedVariables and everything works great now
