Segmentation error with beta 340007 in ui.Image.from_data(...)

[cvp]

ui.Image.from_data(...) gives a segmentation error in

	def pil2ui(self,imgIn):
		with io.BytesIO() as bIO:
			imgIn.save(bIO, 'PNG')
			imgOut = ui.Image.from_data(bIO.getvalue())

Or

o = ObjCClass('UIImage').systemImageNamed_('arrow.up')#.chevron.compact.down')
UIImagePNGRepresentation = c.UIImagePNGRepresentation
UIImagePNGRepresentation.restype = c_void_p
UIImagePNGRepresentation.argtypes = [c_void_p]
UIImage_data = nsdata_to_bytes(ObjCInstance(UIImagePNGRepresentation(o)))
ui_image = ui.Image.from_data(UIImage_data)

Code is old and did work until new beta, 340006 and 340007

Workaround

			imgOut = ui.Image.named('iob:alert_32')
			ObjCInstance(imgOut).initWithData_(bIO.getvalue())
			#imgOut = ui.Image.from_data(bIO.getvalue())

And

ui_image = ui.Image.named('iob:alert_32')
ObjCInstance(ui_image).initWithData_(UIImage_data)
#ui_image = ui.Image.from_data(UIImage_data)
