Version-Release number of selected component (if applicable): 6.10.08-1.fc27


How reproducible:


Steps to Reproduce: 
1. On a fresh fedora installation install root and ipython notebook

sudo dnf install root python3-jupyroot python3-notebook 

2. In an ipython3 shell ROOT imports fine:

[test@localhost-live ~]$ ipython3
Python 3.6.2 (default, Sep  1 2017, 12:03:48) 
Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import ROOT

In [2]:                                                                         
Do you really want to exit ([y]/n)? y

3. Start a ipython3 notebook 

[test@localhost-live ~]$ ipython3 notebook

Expected results:

sucessful import


Additional info:

We encountered this first on Centos 7 EPEL after the root update to the current version. Tested in a fresh f27 VM. The bug seems not to be reported elsewhere so far, googling the error message yields no meaningful result.
