Hi,
it seems to be possible to crash netsurf by triggering an 
assert if in render/layout.c:

503 assert(0 <= block->min_width && block->min_width <= block->max_width);

This seems to work for all html tags that have a width 
attribute (BOX_BLOCK, BOX_INLINE_BLOCK, BOX_TABLE_CELL).

Proof of concept:

Kind regards
Nico
