[GNC] GC 5.10: QIF import does nothing

[Fred Tydeman]

I have Gnucash 5.10 on Fedora Linux 41
I have Gnucash 5.9 on Fedora Linux 40
Both on the same computer sharing the same GC books.

I have a simple two transaction QIF file from Quicken.

When I do File Import QIF on GC 5.10, the menus look OK,
but nothing gets done and no error message.
When I do the same on GC 5.9, it works as expected.

Known bug?
