I suppose you forgot already why this thread started - we ran out of block space and transactions started stacking up, unconfirmed. This almost immediately caused lots of user complaints.

Exactly because people did NOT upgrade to Bitcoin 0.8 fast enough, which fixed the bug in 0.7 and below, now we are now back to square one - stuck with blocks that are too small to meet demand for transactions. Expect the complaints to start again soon unless filtering of SD becomes common.

The options I listed in my first post are still the only options. If you don't want to filter out SD transactions then the default "do nothing" option means that transactions will become very expensive, and small quantities of Bitcoin won't be spendable at all.

The fork is certainly a big problem: unfortunately, nobody realized it would happen. It's not even clear yet what kind of testing would have revealed this issue. Simply making big blocks is apparently not enough to trigger it. That said, we knew that BDB was generally a rats nest of weird problems which is one reason why I ported Bitcoin to LevelDB. If the block sizes had been raised a few months from now, we'd probably have just abandoned the 0.7 users to their fate, but we got unlucky with the timing.

Assuming we want Bitcoin to scale up, we'll have to fork 0.7 and lower off the chain sooner rather than later and then raise the block size limits again.
