error when cancel adding a new card+discussion

The easiest way to attach a picture is to include an image card, like .

But in this case, your description of the problem is already perfect.  I was able to reproduce it and see the issue in the code right away.  I'll try to get this fixed by the next release.

Thanks for the clear and helpful ticket!

this is fixed in Wagn 1.8
