Steps (probably reproducible with a sample with enough items)

 

- Clicked on a favorite (using omnibox)

(note : the item's home grid is some "generic grid" I sometimes use to do some searches, etc. -- as an extra search/scratch grid), 

 

- The grid opens, but  seems like it was originally set to show too many items (that's anecdotal), so IQ warns me (dialog) that the grid will show about 10500 items, and asks me if it should go ahead or avoid doing it.

(Note that this should probably not happen as I just clicked on 1 favorite, a single item, so the grid should load the grid with only 1 item.)

 

- When I pressed "cancel" to avoid waiting for the grid to open with more than 10500 items, IQ crashed.

 

Tried a few times, crashes every single time. Seems like it there's a problem cancelling the loading operation and just show the favorite.

 

(Fixed it by changing the filter in the guilty grid so that IQ doesn't first try to load 10500 items. Works fine after that.)
