Yes, there haven't been any bad transactions for a week now.

There are still people paying to addresses that were exposed by the bug or that were created by the buggy random number generator, but there is nothing BC.I can do about this.

Edit: I should add that bc.i claimed to fix this bug within a few hours.  There is no way to prove this from my end, but the logs support this as more than 75% of the bad transactions occurred during a few hours.  

BC.I has changed to RFC 6979, now.  Thus, the signatures do not depend on the random number generator anymore.
