Comment 1 for bug 1086719

This bug can be reproduced with any classical hazard calculation using the following parameters:

number_of_logic_tree_samples = 1
mean_hazard_curves = false
quantile_hazard_curves =
poes_hazard_maps = at least one PoE

This is issue is caused by an uncommitted transaction in https://github.com/gem/oq-engine/blob/ccdb6713b8a2365ba7414b25fef836453248457b/openquake/calculators/hazard/classical/core.py#L267.

I have submitted this patch to address the issue: https://github.com/gem/oq-engine/pull/971

Note: https://github.com/gem/oq-engine/pull/968 also includes a different fix for the same issue, but 971 address the issue more directly.
