I think this has been reported by someone else recently, but can't 
currently find the reference.  It seems to be due to a new check that 
has been added recently.  What you can do is grep for that account 
number in your data file after decrypting and find what transaction 
contains that split.  Then open that transaction in an older working 
version and check if the category is valid.  If not, change it to a 
valid Category.  You may then find a different transaction with the same 
problem, so you will need to repeat the process.  Apparently at some 
point in the past, it was possible to delete a Category without deleting 
or reassigning all transations/splits which referred to it.
