Line 830:

g_object_get_property (G_OBJECT (widget), pspec->name, &prop_value);

According to the documentation, g_object_get property allocates memory
that must be freed using g_value_unset().

http://www.gtk.org/api/2.6/gobject/gobject-The-Base-Object-Type.html#g
-object-get-property

This never happens, causing a memory leak. Below is a valgrind log
illustrating the problem. Note the line numbers are slightly different
than the line numbers in trunk, but it seems clear what the problem is.

==4864== 790 bytes in 100 blocks are definitely lost in loss record 4,263 of 4,374
