Dear @theayon ,

Thanks for this bug report. I am sorry you are experiencing this problem.

We are aware of this issue and are working on a fix. The current workaround, if that can work for you, is to revert the update, until the fix is merged in the repository. Or, and this is a really a kludge, you could try to configure ROOT without modules.

Dear @dpiparo

Thank you for addressing the issue. I try the workaround in the meantime.

Hi @theayon , pinging you directly. Thanks again for this report. As you can see from the link above, thanks to @vgvassilev, we have a solution in the master branch of ROOT.
