Short description of error
If there is a second Outliner with a filter that does not match anything and you drag a collection from the first outliner over the second outliner, dragging gets stuck and Blender crashes (Segmentation fault (core dumped)).

Exact steps for others to reproduce the error
In the default scene, split the Outliner area in two,
add a search term to the new Outliner that does not match anything (like "8" or "[" or "test"),
drag a collection from the first Outliner down towards the buttons area.
Dragging will stop at the bottom of the header of the second Outliner and Blender will crash shortly after.
