Uncaught TypeError: Cannot read property 'source' of undefined

[blay]

1. Task list open. No other packages in atom except themes.
2. Move a card to a new column (i.e. from TODO to DONE) OR move the priority of a card up or down a list.
3. Sometimes works, sometime get error "Uncaught TypeError: Cannot read property 'source' of undefined"
4. Task list freezes and circles forever.
5. Close task list and open it again. Rescans and the card is in the new location as should be.

I experienced the same error but after closing the error alert and the IMDONE tab and pressing alt + t
again, I see it updated.

Also got this error when clicking a "Down arrow" in the to-do list to see what it would do.

After closing error popup and imdone tab, then reopening things seem to be working again.

I'm no longer maintaining imdone-atom, but a stand alone electron app is available at imdone.io
