I upgraded from 42.2 to 42.3 a couple of weeks ago - now gnucash won't run; it coredumps on startup :-( There are no pending updates, and the only non-standard repo I have is Packman. I can still access the gnucash data file from another system (Windows) with no problems.

Code:
> zypper lr

i+ | gnucash | package | 2.6.18-98.1 | x86_64 | Gnome Apps            
    filelist: /usr/bin/gnucash

i+ | gnucash | package | 2.6.18-98.1 | x86_64 | (System Packages)     
    filelist: /usr/bin/gnucash

If I "upgrade" to the GNOME version, it crashes the same way.
If I open a new blank data file, it works with either version.

CRITICAL NOTE: The 2.6.16-98.1 version worked correctly on LEAP 42.2 - that's the version I was running prior to the upgrade

How can we debug this?
