Double quotes in ODT comments cause exception in Renderer

To reproduce:
- create an ODT document with some paragraphs
- select one of them and add a comment, saying: do text if mydict["mybool"]
- in Python, pass this to the renderer as the context variable: {"mydict" : {"mybool":True}}

The expected behaviour is to see the paragraph printed in the output.

Instead, the Renderer crashes with the log output similar to this:
