Hi @wired
This issue is the same as Crash on Histogram request and recorded in Issue #67. Issue #67 has already been fixed and was scheduled for the end of April. Since you have already ran into this issue in a different form, I have created an interim fix 0.8.10 alpha release. See the download page, or download 0.8.10 Win10 directly.
We do not plan on fully testing this release since it is out of cycle. Despite that, the changes affect program execution, not current, voltage, power, or energy compuation, so we are reasonably confident that you will not see regressions with this release.
