Hi,
in [1], Ihor fixed a bug I reported in ox-odt. Unfortunately, this fix
broke figures with several lines of captions such as:
#+CAPTION: first line,
#+CAPTION: second line
[[file:media/myPicture.png]]
This is because, in this case, org-odt-plain-text is called at some
point with " " as value for `text`. In this context, both `leading` and
`trailing` temporary variables contain the same value as `text`, making
the `substring` call crash.
The attached patch fixes the issue by considering that there is no
leading/trailing content when the input only contains spaces.
