Sandro, thanks for your reply. You're right about "folding postgis 7 times" :-)
I'm having difficulties in isolating the offending geometries, which is mainly
due to my lack of knowledge.
When I look at the location at 59647.5 392932 there is no intersection. Only
when I use buffer(geom,1) there are two objects, one of them being a funny line
of three points but still identified by PG as polygon.
So I'm a bit lost now. I will continue to try to isolate a few features to
consistently reproduce the problem.
Ge

Well, it's a robustness problem.
Try folding a piece of paper for more than 7 times. It's a similar issue.
If you can isolate the offending operands I might take a closer look.
Please file a ticket for it.
