Bug#515722: libgtk2.0-dev: gdkspawn.h fails G_DISABLE_SINGLE_INCLUDES check "Only <glib.h> can be included directly."

[Steve Cotton]

Package: libgtk2.0-dev
Version: 2.12.12-1
Severity: serious
Justification: root cause of #515679 (xlog FTBFS)

GTK apps that use the GLIB sanity check G_DISABLE_SINGLE_INCLUDES don't build.

steve at localhost:~/temp$ cat includegtk.c 
#include <gtk/gtk.h>

int main(int argv, char** argc)
{
        return 0;
}
