On styles lost during overflowing text transfer - warnings of Draw

Hi there,

as I mentioned in the past, the current implementation seems to lose styles
here and there when transferring text.
Could this be related to some warnings I'm getting during the execution of
Draw? If not what are these anyway?
Here I'm pasting some:

warn:legacy.osl:13760:1:svl/source/items/style.cxx:458: Incorrect index
