Hi, There seems to be a memory leak in the implementation of dialogs in GTK2.
I compiled a form containing only a button and a TOpenDialog using yesterday's Lazarus snapshot and the heaptrc unit. If the dialog is opened and closed by using either of the buttons, when the application is terminated I get the output given below. It seems that the TFPList variable named FilterList which is created in line 113 of gtkfiledialogutils.inc is not being freed but I cannot work out where it should be freed. Hope someone can help.
