+/**
+ * Bug on Android >= 4.2
+ * 
+ * http://code.google.com/p/android/issues/detail?id=41901
+ * 
+ * DialogFragment disappears on pressing home and comming back. This also happens especially in
+ * FileDialogFragment after launching a file manager and coming back.
+ * 
+ * Usage: <code>
+ * DialogFragmentWorkaround.INTERFACE.runnableRunDelayed(new Runnable() {
+ *          public void run() {
+ *              // show dialog...
+ *          }
+ *      });
+ * </code>
