builder demo about dialog segv

[tedx]

I just started looking at go gtk support and see this segfault on my RHEL6 box. Is this a known issue? I'm using: go version go1.7.3 linux/amd64

fatal error: unexpected signal during runtime execution [signal SIGSEGV: segmentation violation code=0x1 addr=0x7ffcbf8ad000 pc=0x54dd6b]

Exact same crash with current go version go1.9.2 linux/amd64 on up-to-date Ubuntu.

I get the same with go version go1.10.3 linux/amd64 on up-to-date Debian.
