[pygtk] TextBuffer, Python 3 and UTF-8

2011-07-23 Thread Osmo Salomaa 
Hi,

I'm migrating an application to Python 3, GTK+ 3 and the PyGI bindings.
I'm having trouble inserting non-ASCII text to a Gtk.TextBuffer. Here's
a minimal example.

#!/usr/bin/env python3
from gi.repository import Gtk
text_view = Gtk.TextView()
text_buffer = text_view.get_buffer()
text_buffer.set_text("åäö")
text_buffer.insert_at_cursor("åäö")
window = Gtk.Window()
window.add(text_view)
window.resize(500, 500)
window.show_all()
window.connect("delete-event", Gtk.main_quit)
Gtk.main()

The 'set_text' call seems to always succeed, but the the following
'insert_at_cursor' call fails with

Gtk-CRITICAL **: gtk_text_buffer_emit_insert: assertion
`g_utf8_validate (text, len, NULL)' failed

The same is true of the other 'insert_*' methods. Strangely trying to
insert "åäö." instead of "åäö" doesn't give a warning, but doesn't
insert the period.

Is this related to the string type changes in Python 2->3? Can I expect
Python 3 and non-ASCII text to work in general with PyGI? I'm using
Python 3.2 and PyGObject 2.28.6 on Debian unstable/experimental.

That's strange. There should be an entry like this:

Don't see anything too weird in there.

Looks good. Next step:
- launch a "Command Prompt" (aka cmd.exe)
- start depends.exe [1] from the "Command Prompt", for example
   type C:\depends.exe and then hit the return or enter key
- File>Open>"C:\Python27\Lib\site-packages\gtk-2.0\runtime\bin\glade-3.exe"
- hit F7
- check all the checkboxes
- click "OK"
- Glade now starts. And will crash like you've described above
- Back in Dependency Walker click File>Save As...>glade-3.dwi
- Upload the (compressed!) glade-3.dwi file somewhere and let us
  know where we can get it or mail the file directly to me (don't
  try to post it on the mailinglist, you message will be rejected
  due to the attachment being too big...)

mvg,
Dieter
