[Vm-dev] Reproducible Cog crash from image startup

[Eliot Miranda]

Hi Mariano,

     I need the changes file to reproduce this without a notifier stating
that the changes file is missing.  Could you send me it asap?  BTW, it does
crash on my Cog.  But it will be easier to debug with a changes file.  Thx
