Docutils parsing errors leads into unloadable algorithm

If the long description of an object does not parse well, the said object does not load properly. For example:

https://www.beat-eu.org/platform/algorithms/AntonioCandia/hist/1/

Expected result: if there is a parsing error with the long description of an object, we should fallback to displaying the unformatted (code-style) documentation, together with a warning message indicating the problem.
