In one of these "not particularly useful" comments, I'll say I recently found an infinite loop in/around the linepatternsymbolizer in 0.6, but couldn't isolate a sample of the (proprietary) data - after much binary chopping I deduced it needed at least 3 of the relevant linestrings to trigger it. Upgrading to 0.7.0 made it disappear, as did disabling the linepatternsymbolizer in 0.6, but I couldn't see anything in 0.7.0 that indicated it had been discovered or deliberately fixed. Like I said, not particularly useful, but something to be aware of.
