Update of bug #55736 (project octave):

                  Status:               Need Info => Ready For Test         


Follow-up Comment #8:

It looks to me like the problem doesn't depend on whether docs are enabled,
but instead whether the call to m_help_engine->setupData () succeeds in the
constructor for the documentation class.  If it fails, then the constructor
returns early and the doc browser is not fully constructed.  If docs are
disabled, there is no warning about that either.

I pushed the following changeset that seems to avoid the crash if the help
engine setup fails:
