Hi!
I use gda with Apache module, and recently I am testing memory usage with
valgrind.
There's gda_init call when Apache starts, and plenty of like these in
valgrind's report:

I know that GType system data are almost always reported as "still reachable"
but I am not sure
about those initialized with libxml.
Should I consider this as memory leak or can I ignore these reports?
