Fixed for next release/beta. The error was in formatting a message when
the assignment failed because the value could not be opened. Only
multiple assignment was affected.
Thanks for the very clear report.

The problem was that u@.m, which should be a domain error, crashed

The Right People are looking into it. It crashes after the dialog box
is dismissed and execution returns to JQt, or perhaps later when JE goes
for the next sentence.

I have more information.
plot puts up the dialog in qt_paintit:
info ({.~i.&LF) 13!:12''
and then exits after the user presses OK. The crash happens after that,
so it's either back in JQt or in the JE on the next sentence.

When I ran this, I got a crash. But I know I am running a mongrel
system, with old JQt and unreleased JE. Since others report no error,
perhaps that's our problem? You could try making sure your JQt is up to
date.

Do you mean that jqt807 on Win10 does not crash, while a newer J crashes
on your iPad?
I noticed more crashes in the past
