Sampler note-off layer crash

In the “Samples” area of the Sampler (with the “Samples” area in focus/selected):

Renoise crashes when I attempt to paste samples into a “note-off layer” or “note-on layer”.

This is the error:
A fatal error or crash occurred (unhandled exception in thread: GUI).

System specs:
Renoise 3.2.1 (64-bit)
Windows 10 (64-bit)

Thanks for the detailed report. Will be fixed…
