Nice!

I should add that I've seen this error even without openocd connected,
so this seems to be a real error. Anyway, I guess this will sooner or
later be applied (in some form) upstream, so openrd should benefit
"automatically" from it.

However, with OpenOCD there are other type of crashes which look very
random, so I believe those will stay even with this.
