new crash in master

[Jack Ostroff]

First, thanks for all the help and quick work dealing with everything  
I've been adding to Issue 61.  All my original crashes and other issues  
are fixed or are  being worked on.  This was all for reconciling a  
bunch of investment accounts and a checking account, so it was a pretty  
good exercise of most of what I do with KMM.

This is a new crash over the past few days.  It's pretty consistent:   
start KMM, go the the ledger for an investment account, click  on the  
Investments View, crash.  So far, I only found two accounts which do  
this.  If I start with the Investments View and select the account,  
then go to the Ledger and back, no crash.  If I select any other  
investment account first, I can 't get it to crash.  I just finished  
reconciling a whole bunch of my investment accounts, so it doesn't seem  
likely there is anything seriously wrong with any of them, including  
the one that triggers the crash.

Console output might have another hint:
First, when opening the investment account in the ledger:

No selections
current selection
Institutions: ("I000005")
Accounts: ("A000344")
JournalEntries: ("2022-07-01-T000000000000025933-S0002")
current selection
Institutions: ("I000005")
Accounts: ("A000344")
JournalEntries: ("2022-07-01-T000000000000025933-S0002")

That transaction is just the last transaction displayed in the ledger  
for that account.  Then, when selecting the Investments View:

No selections
No selections
No selections
QSortFilterProxyModel: index from wrong model passed to mapFromSource

Thread 1 "kmymoney" received signal SIGSEGV, Segmentation fault.
0x00007ffff5e59a37 in ?? () from /usr/lib64/libQt5Core.so.5

The mentioned transaction is a Dividend transaction in both cases, one  
marked as imported (not yet accepted) but accepted and reconciled in  
the other account.

Anything else I can do to help troubleshoot?  This is with kmymoney  
5.1.80-aa17abb7e.
