Invalid view definition of move line with journal view
Error when opening moves of a journal if the journal has a custom view definition it raises and error because there is an invalid colors definition [1].
The attached patch fixes it.
Trunk and 3.8 versions are not afrected, but we found it on 3.4 series, but 3.6 is also affected.
The attached patch is based on 3.6 and fixes it.
