* typically created using the following code snippet:
* <informalexample><programlisting>
* gchar *history = pika_personal_rc_file ("profilerc");

*
* The recommended @dialog type to use is a #PikaColorProfileChooserDialog.
* If a #PikaColorProfileChooserDialog is passed, #PikaColorProfileComboBox
* will take complete control over the dialog, which means connecting
* a GtkDialog::response() callback by itself, and take care of destroying
* the dialog when the combo box is destroyed.
*
* If another type of @dialog is passed, this has to be implemented
* separately.
