Weird OS10.1 crash

[Andrew McVeigh]

One client, one Mac 10.13

A list is loaded and the user can double click to select an invoice to be paid from the list, then Omnis crashes with the attached report

Open back up and do the same thing and it works

The next morning, different invoice same result for the first double click of the day, from then on all works fine

I have stepped through the code and of course it never fails and crashes

Any masters of the crash reports can get a clue from this? There is a heap more of course but this looks like the vital part
