[GNC] Gnucash 5.5 crashes on CSV import

[Ed Greenberg]

I'm running the Gnucash 5.5 that comes with Ubuntu 24.04 LTS. 
Specifically, Version: 5.5 Build ID: 5.5+(2023-12-16) Finance::Quote: 1.59

I imported a CSV a while back, (first few lines shown below) but now I'm 
getting an unexpected program crash.  I'll show the first few lines of 
the log under the first few lines of the import file.

Log file shows nothing of value:

mod    trans_guid    split_guid    time_now    date_entered    date_posted    acc_guid    acc_name    num    description    notes    memo    action    reconciled    amount    value    date_reconciled
-----------------
===== START
===== END
...plus additional lines of START and END

My columns were set as:

Date,Description,Commodity,Number,Full Account Name,Amount,Value,Price,Reconcile,Transfer Account

Notes:

I set the date, properly, for m-d-y and I set Character Separated and 
Comma.

I get as far as the "Import Preview" screen, and then the "Match Import 
and Gnucash accounts"  but never get to the "Match Transactions" page.

The program just "Goes Away"  It leaves it's lock file behind.

If the Import settings were freshly created, even if the green save icon 
was hit, those settings are not available when restarted.

That's about all the observations I have.

Does anybody have any ideas? Should I open a formal bug? Uninstall and 
install 5.9 from a flatpack? Anything else?

Thanks,
