Panic on gui/splitter #1

Closed hgfischer closed 7 years ago

hgfischer commented 7 years ago

While sequentially exploring the demo, I got the following exception when I was testing the splitter demo.

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x418 pc=0x5e0572]
