Hi Oscar,

to get some help, you should simplify the code you've posted: the
longer the pasted code is, less likely that someone will take time to
compile it and check for the problem. If you'll be able to isolate
your issue into few statements, there's higher chance you'll get some
advice.

Even better if you translate the code to Python code so that people
can try it directly e.g. from qgis python console...
