Wild guesses follow:
Did the local effects change the font size so that the selection
contained multiple font sizes?
Had the cursor been positioned between the close of a previous font
size and the open of a next font size? e.g. if the cursor is the pipe
(|) in the following is font size not defined and therefore returned
as zero?
<12pt>some 12 point type</12pt>|<10pt> and some 10 point</10pt>
Distracting comments follow:
Depending on what you are doing, you may need to consider the line
spacing rather than the size of the text to define your bounding box,
eg by combining getleading() and getfontsize() appropriately for the
format returned by getleading().
Lock to baseline grid can also have a dramatic affect line spacing.
Hoping there is some sense and relevance in this response.
