I get a segmentation fault after lots of 'libfo-CRITICAL' messages. The first
one is

(process:12015): libfo-CRITICAL **: fo_area_page_size_request:: Cannot split child:: page: 
FoAreaPage (0x9e8ddb8 : 2); child: FoAreaViewportReference (0x9e8dcb8 : 1)

which I assume your latest work was meant to resolve. Right ?

The second such message looks like an identical copy of the first, but the third
one is strange again:

(process:12015): libfo-CRITICAL **: Expression evaluation error: Expression not completely 
evaluated: '/ast.svg'
Object path: 
/FoTree[1]/root[1]/page-sequence[5]/flow[1]/FoBlockBlock[2]/FoBlockLayout[3]/external-graphic[1]

The expression in question seems to stem from an external-graphic attribute
src="images/ast.svg". I thought xmlroff is able to deal with such paths. Do I remember
wrongly ?

The last errors, which appear to have caused the actual segfault, are assertion errors
such as:

(process:12015): libfo-CRITICAL **: file fo-length.c: line 320 (fo_length_get_value): assertion 
`length != NULL' failed

Let me know if I can help debug this further.

Thanks,
		Stefan
