On further testing of the patch and sent it to the list I got memory
corruption problems similar to what you described how did you get glib
to detect the double free ?
If you can get a gdb trace that would be fantastic I'm trying to run
valgrind now but its painful. For now I'm going to assume that the
patch is correct and see if I can find the double free. Anyway trudge
trudge trudge :)
