Re: unison gui crash with backtrace

This looks very much like https://urldefense.com/v3/__https://github.com/bcpierce00/unison/issues/990__;!!IBzWLUs!Xb5Ag7rx2BATQ5OmSlJIzVZ8nnErOAj7SMFjwZCdlUY6i8zmEey4EJUAjSetysz2pGfD7eP6ta3EjtMKXFVkUg$ 
Please add to that ticket even though it's closed (it will be reopened).
Can you extract the very start of the stack trace, too? Could you also add
more information on what you were doing, how many updates were being synced
and at what point the crash occurred (the latter will hopefully be visible
from the start of stack anyway).

Do you have the possibility to try without the GUI?
