OpenVZ bwm-ng disk IO stats seg fault?

Various different OpenVZ based VPS, bwm-ng tool and pressing "n" twice to switch to input: disk IO type: rate
results in Segmentation fault whereapon it dies and returns to the shell.

I can't remember if it worked before, maybe the 64 bit kernel upgrade due to the vulnerability caused it, but it definitely does work fine under Xen based VPS (makes sense that it would though).

iostat also doesn't seem to work properly, so probably it is something to do with how bwm-ng is grabbing disk usage data stuff?\

Don't actually need an answer, probably should submit a bug report somewhere, but someone else might be able to do that or suggest a fix?

Bug report exists for OpenVZ kernel 2.6.18 about a non-working diskstats. Not sure which kernel the fix ended up in?
