Also has some errors from depsgraph cycles, not sure if related:

I looked into this for a bit and here is what I can make out:

  • We're in channel_list_build_keylists and it's called with a range of (-5.125, 46.125).
  • Going into summary_to_keylist then fcurve_to_keylist.
  • Before f3b393a74a update_keyblocks was called with the BezTriple at the start index with the number of indices in the range.
  • After f3b393a74a it's called on the whole fcurve.
  • In add_bezt_to_keyblocks_list the assert is hit because we ran out of columns in keylist->key_columns and all of them are < 52 (where the bezt[1].vec[1][0] is).

I think the only real solution is to make sure that transforming keys in the dopesheet sorts them during transform just like it does in the Graph Editor.
Will work on a patch for that
