Possible bug in GdlDockLayout or Python Bindings

[Micah Carrick]

Hey guys, I'm not quite sure who to contact regarding the gdl python
bindings or which project the bug should be submitted to (I don't know
much about language bindings). Another user posted this issue back in
Feb. of last year:
http://www.mail-archive.com/gnome-devtools@.../msg00335.html

However, it was left unresolved. I've done a little testing and have
some more information.

The problem is with loading a GdlDockLayout from a file. I've built a
little test application in C and another in Python. The one in C works,
where as the Python one does not. When the Python application loads the
layout from the file, it looses all dock items. I've attached the test
applications to this email. These test programs save the layout when to
close, so you'll have to run it once, close it, and then run it again to
see the bug.

If anyone could take a quick look and a) make sure I'm using gdl
properly (docs are limited) and b) suggest whom I might contact and/or
submit a bug regarding this problem and c) any suggestions for a quick
fix would be great. Who is maintaining the gdl python bindings?

Regards,

Hi!

Actually, I have no idea who really wrote the python bindings for gdl.
Anyway, as far as I know they should be mostly autogenerated but you
might want to have a look at the gnome-python-extras module on
git.gnome.org to see if there is any custom code that might break
things.

Regards,
Johannes
