Cannot creat a rule for a transaction for its amount to be added to a piggy bank

[gregblink]

Couldn't reproduce it in demo site unfortunately, so the problem obviously comes from my end.

I stripped the transaction and the piggy bank out of their fanciness, they're bare naked, there's no categories, none belongs to a group. It simply won't do, and i dunno why. The exact same thing works flawlessly in the demo site.
Here after a screencap of the error message.

I know, it's a bug :(

The ticket has been closed, sorry about that. You weren't able to find it I guess. But it's duly noted and a fix will be part of the new release.
