Cyril Scetbon commented on TINKERPOP-2315:
------------------------------------------
[~spmallette] there is something really weird happening in an iPython session.
the clone works well but as soon as I check the value of the traversal, I can't
use it anymore ...
{noformat}
In [28]: graph_traversal = traversal.V().hasLabel('OID')In [29]:
graph_traversal.clone().limit(10).count().next()
Out[29]: 10In [30]: graph_traversal.clone().limit(10).count().next()
Out[30]: 10In [31]: graph_traversal
Out[31]: [['V'], ['hasLabel', 'OID'], ['values',
'_ipython_canary_method_should_not_exist_']]
In [32]: graph_traversal.clone().limit(10).count().next()
{noformat}
It gets stuck on the execution of In[32]. Sometimes I even get
{noformat}

Can you check what's going on ? I used the latest 3.4.8
