XRC and xmlres.cpp : memory leaks?

[ATS]

Using a memory leak tracer I get a number of leaks reported after using XRC
resource loader: 

I've gone over my sources and I'm pretty sure I've released everything that I've
been using, including freeing the wxXmlResource object. Also I'äve single
stepped through this and know that the objects the app use from XRC are released
before running the leak tracer.

The leaks are proportional to the number of objects loaded, so if I load a
dialog twice I get double number of leaks. 

Below are some output from the tracer.

Platform is 
- wxW 2.9 (based on SVN, approx 2 months old), 
- Ubuntu Feisty Linux.

Regards
