can't move transactions from investment account?

[Jack]

I just tried to move a transaction from one Investment Account to  
another Investment Account.  I can select the transaction, right click  
for the context menu, select Move to..., but the popup says "Asset  
accounts" and the list is empty.  Moving transactions from other types  
of accounts seems to work fine.  I don't remember when I last did this,  
or if I actually ever did.  This is with a version freshly compiled  
from git master (just minutes ago.)

I obviously have no idea if this has long been the case, or if it's due  
to any recent change(s).  I'll file a new bug if it needs tracking.
