Re-hallo,
Ok, the case is now solved.
I made the model too complicated.
I need only to create gtk.ListStore() and that's it. There is no need to
go via model_sort.
model_sort = gtk.TreeModelSort(model)
self.set_model(model_sort)
This works really well:
model = gtk.ListStore(gobject.TYPE_STRING, # Filename
gtk.gdk.Pixbuf, # Icon image
gobject.TYPE_FLOAT, # File date
gobject.TYPE_INT) # File size
self.set_tooltip_column(COL_THUMB_FILENAME)
self.set_text_column(COL_THUMB_FILENAME)
self.set_pixbuf_column(COL_THUMB_PIXBUF)
self.set_model(model)
# Make iconview sortable
# Compare function is not actually needed. The default (internal
cmp) function is good enough.
# model.set_sort_func(COL_THUMB_FILENAME,
self.default_sort_compare_func)
# model.set_sort_func(COL_THUMB_FILESIZE,
self.default_sort_compare_func)
# model.set_sort_func(COL_THUMB_FILEDATE,
self.default_sort_compare_func)
# Set default sort order
model.set_sort_column_id(COL_THUMB_FILESIZE, gtk.SORT_ASCENDING)

Here is a fully functional test code:

It rocks!

Hello,
I have a small application that shows thumbnail-images in a
gtk.IconView widget.
The thumbnails are sortable on filename, file size and date. The
sorting seems to work fine.
But the program crashes when I try to reload the thumbnails.
Here is a picture of the application.
http://bildr.no/view/595635
When I press the [Reload thumbnails] button 2'nd time, the program
crashes with "Segmentation fault".
No other error messages appear.
The crash happens at self.clear_display() function. It simply finds
the model/ListStore and clears it.
model_sort = self.get_model()
model = model_sort.get_model()
model.clear()
Can you help me to spot the error.
The first version was un-sortable and it worked very well. But I
really want to make it sortable.
Here is a test-code: http://www.futuredesktop.com/tmp/Test6.zip
My system is Ubuntu Linux 9.10, 64bit.
