problem with newer pygtk

[GoogleCodeExporter]

Got the traceback below with released pychess using 

glib2 2.12.12
gtk2 2.10.11
pygtk 2.10.4
pygobject 2.13.1

If i change line #64 in BoardPeview.py
from
        self.widgets["mainvbox"].unparent()
to
        self.widgets["mainvbox"]    #.unparent()

it runs with a warning only.

Well, with 
glib2-2.12.9
gtk2-2.10.8
pygtk2-2.10.4
pygobject2-2.12.3

I get this warning when removing the unparent line:

/home/thomas/Programmering/python/skak/0.7/lib/pychess/widgets/BoardPreview.py:6
8:
GtkWarning: Attempting to add a widget with type GtkVBox to a container of type
GtkAlignment, but the widget is already inside a container of type GtkWindow, 
the
GTK+ FAQ at http://www.gtk.org/faq/ explains how to reparent a widget.
  self.add(self.widgets["mainvbox"])

And when I open the load game dialog the previewboard doesn't show up.

The error you posted was given to you in cases where you did have the unparent 
line,
correct?
It is strange how self.add(self.widgets["mainvbox"]) complains that
self.widgets["mainvbox"] but self.widgets["mainvbox"].unparent() doesn't seam 
to do.

The problem might however be related to this: http://www.gtk.org/faq/#AEN636
In which case it should be fixable by replacing the unparent line with
self.widgets["mainvbox"].get_parent().remove(self.widgets["mainvbox"])
or perhaps even self.widgets["mainvbox"].reparent(self)

All three versions work fine for me.

"The error you posted was given to you in cases where you did have the unparent

Yes.

self.widgets["mainvbox"].get_parent().remove(self.widgets["mainvbox"])
doesn't worked(got tracaback).

self.widgets["mainvbox"].reparent(self)
worked with warning, and the preview was ok too.

Tried all with 0.7 svn.

After your last commit i tried it again, and pychess doesn't started again.
Then i rereaded all our conversation from beginning, and discovered my versions
doesn't match. pygobject 2.13.1 !!!
After downgrading pygobject to 2.12.3, your original code (unparent) worked 
without
any problem. So it was my bad. Sorry for misleading you!
