OK, I can get this error too.

Rewriting the "save snapshot" function is on my todo list since some 
time, because there's something wrong in the current logic for which I 
already had to add some hacks (basically, the "save" method is called 
while processing the current VBL interrupt, instead of postponing it 
after the current instruction is completely processed).

This requires some rather low level changes (interaction with cpu core) 
to change this, hopefully I will have more time later to work on this, 
but at the moment I'm really busy with too many things to work as much 
as I would like on Hatari :(
