Segmentation fault on buffer commands to playground buffer

[kaddkaka]

Neovim crashes with segmentation fault in at least these two scenarios (Not sure where the problem resides):

1. Toggle the playground buffer and show it as the only window: Do :bd -> crash!
2. Stand in the playground buffer (doesn't matter if other windows or buffers are open): Do :bp -> crash!
