Cross Crash When Removing Playlists from Sidebar

I have three playlists in the left-sidebar of Cross. I no longer want them there.
I drag them to the centre collection library panel to remove them and the first two disappear correctly. If I remove the third, Cross crashes.
Here's the crash report:
If I restart Cross, all three playlists are still there. It doesn't matter in what order I try to remove them, on the last one Cross crashes.
