Gnucash Crashing

[J.L. Sundstrom]

Recently upgraded to 10.13.3 and had to upgrade Gnucash (GC 2.6.19) to work with it.  All was well until installing “recommended” update to 10.13.3 (character sequence can cause crash) on 2/22/18.  After that, opening and closing GC and then trying subsequent opening GC crashes (Apple info available if wanted).  Discovered work-around of reinstalling GC which opens the app and I can use it without problem.  But, close it and try to open again… it crashes.  Any ideas why this would be the case?  It appears that Apple’s update broke 2.6.19.
