Steps to reproduce:

1. File->New File
2. Accept all defaults in account setup wizard
3. Save the new file
4. Open Assets:Current Assets:Checking Account
5. Create a new, split transaction as follows:

Description: test
Deposit 1 in Assets:Current Assets:Checking Account
Withdraw 1 from Income:Salary
Deposit 2 in Assets:Current Assets:Checking Account
Withdraw 2 from Income:Salary

6. Record the transaction
7. Click on the 2nd line with the description "test" and open the split
8. Click on the "n" in each of the reconcile status fields to turn them to "c"
9. Click on the blank transaction at the bottom
10. Click on "Discard changes" in the "Save the changed transaction?" dialog
11. Open the split in the 2nd "test" transaction

At this point I expect to see "n" in the reconcile status column of each sub-transaction, but the last 2.00 withdrawal from Income:Salary has a "c" in it.
