Error occurs in the combination of <fo:inline> of font-size="smaller"/"bigger"
within <fo:block> of font-size in percentage. The error is "getBaselength
called without context".

<fo:block font-style="normal" font-size="80%" role="html:div"
<fo:inline baseline-shift="super" font-size="smaller"
role="html:sup">th</fo:inline>of each month.
</fo:block>

OK, now I see it too.

I'll run it through the debugger, but already think I know what is going on.
The property resolution mechanism tries to resolve to smaller/larger font-
sizes too early. Percentages are resolved (mostly
anyway) during the layout-stage, where FOP tries to already resolve
the "smaller" keyword long before that.

I haven't tried yet, but using em's could also lead to trouble in combination
with percentages, as in:

<fo:block>
<fo:block font-size="80%">
<fo:inline font-size="8em">

Will keep you posted.

Cheers
