Comment 6 for bug 585688

I guess an important question here is: are you using federatedx tables?

I suspect that you are not, which makes the crash even more strange.

The stack trace does give us a good clue as to where to look for the problem:

get_all_tables() is calling ha_federatedx::info() which calls federatedx_txn::release_scan(), which crashes.

So what is federatedx doing that makes it crash if it actually has no tables?
