            Bug ID: 4478
           Summary: Crash on keyboard navigation past start or end of
                    message after starting with 'ssh -X host claws-mail'
           Product: Claws Mail
           Version: 3.17.8
          Hardware: PC
                OS: OpenBSD

Scripts containing the three runs and some system configuration detail.

The two scripts in the attachment demonstrate:
webclient$claws-mail working without crashing.
monitor$ssh -Y webclient claws-mail working without crashing.
monitor$ssh -X webclient claws-mail crashing.

In all three runs I opened a Compose window and pressed the 'down' navigation
key.

Some time ago, possibly at least two years, 'ssh -X ...' would not start
claws-mail and I used 'ssh -Y ...'.  As soon as I noticed 'ssh -X ...' would
start claws-mail I changed monitor's .fvwmrc configuration file to use 'ssh -X
...' but did not see the problem until I had forgotten the change.  Since then
I just tried to avoid the problem keypresses at the wrong time until I tried
'ssh -Y ...' earlier today.  (Note that webclient is a testing box which had
claws-mail added earlier today specifically to do these demonstration runs.)

Replacing webclient by a FreeBSD 13.0 box leads to the same problem.

Apologies if I have chosen the wrong product (Claws Mail GTK-3 looked plausible
too).  I am not convinced about the component choice either, but that is where
I encounter the problem most.
