I can reproduce, but this only seems to happen with new entries -- if all the content is removed from an existing entry the image widget still works for me.

#829 partially affects this, but it doesn't seem to be the main cause -- If an image widget is added, it still seems to "crash", just not quite as hard.

Looking at Redux, on initial load entryDraft.entry.data.body is set to null instead of an empty string. Only when it is null does the image widget crash.

@tech4him1 moved that bit from your last comment into a separate issue, #956.

[tech4him1]

@erquhart No, my comment is not talking about the alt text being null. My point was that entryDraft.entry.data.body should be set to an empty string initially, so that the image widget didn't crash.

@erquhart I believe the null crashing part was fixed in #955.

Ah, I see what you mean. Yeah that's a general problem, not sure why things are being set to null. I would assume it's somewhere in our Redux implementation.

Opened #977 to address.
