[GNC] Crash - GnuCash 5.12 on macOS 26 Tahoe

[Steve Waltner]

I upgraded to the new macOS Tahoe 26.0 software earlier today. One of the risks of installing the new OS releases on the first day is incompatibilities. GnuCash has been pretty stable for me, but I’ve had a couple application crashes. At least one of them happened as I was trying to switch between two GnuCash data files (one for me and one for my dad).

GnuCash 5.12-1 (ARM)
Mac mini M4
macOS Tahoe 26.0

I have since upgraded to GnuCash 5.12-2 and will keep an eye on the program. I don’t think the difference between the 5.12-1 and 5.12-2 versions will matter since the announcement for that release mentioned a GTK bug with displaying contextual menus.

The first part of the Crash Report in the console application is as follows:
