Yes there are, available from the Picard download page. Could indeed be related, but the fix does probably not apply to OS X. @ldexterldesign can you test the nightly development build and see whether this fixes the issue.
The ticket is still open, so it hasn’t been fixed, and @Zas wants to put 1.4 ASAP, so it’s unlikely to make it in, unless someone suddenly steps up with a patch.
It is possibly it has been fixed as a side effect of PICARD-761, so it would be great to hear back whether 1.4 nightlies fixed the issue for affected users.
