Nice to hear from you. Yes, for 1.52 many bugs were fixed. I'm currently 
also fixing some bugs.

Yes, I prefer that this issue is filed as a ticket. Especially after 
such a long time, and there were several items at that time, I cannot 
remember which was this issue and what I researched (though I can find 
these WKT's in my programs indeed).

Please file them separately, unless you already know it is the same 
issue, if that is the case, please combine them. Separate tickets are 
handy because I can close them if fixed, and continue with the next.

There are still some tickets in the Trac, but I also solved several, 
last months.

Was this the issue with the spikey polygon going forwards and backwards 
over the same line? I remember that this was one of the issues you had. 
If that is the case, it will probably take longer to solve because I'm 
first concentrating on valid polygons...
