Such bugs are tightly related to the version of the GTK libraries (and their
python bindings) you are using.

Please, can you tell us what distribution, versions of GTK and python-gtk you
have?

[clubber (fkramer)]

Hi guys we experienced the issue as well and can for us creating a entirely new Ubuntu User solved the problem. So for the moment the problem doesn't seem to be related to packages in the first place but rather to configuration of the GTK environment.

Can you check which "engine" is the Gtk theme using at each case?
GTK engines are C programs and sometimes influence the allocation/deallocation
of "objects" at that framework. Then, Python may find itself tracking a wrongly
referenced object..

Still unable to use OpenERP with GTK Client.

[Antonísio Prúcoli Martins (antonisio)]

Hello All!!!
I had same problem on Gentoo.
I forced Gentoo to update gtk+-2.20 to gtk+-2.22, pygtk-2.17 to pygtk-2.22 and all related packages (12 hours compile and check all!!!).
Now, OpenERP GTK Client is running fine!!!
I don't invertigate this problem in deep, but, I think that It's a gtk and pygtk problem.
Thanks!!!

[Denis Konchekov (dkonchekov)]

Have same problem (but only error strings "Fatal Python error: GC object already tracked" and "Segmentation Fault" without traceback). Client crashes when I double click records (for example leads).

OS: Ubuntu 10.10 (maverick)
gtk2-engines: 1:2.20.1-1ubuntu1
libgtk2.0-0: 2.22.0-0ubuntu1
python: 2.6.6-2ubuntu2
python-gtk2: 2.21.0-0ubuntu1

[Anders Wallenquist (aw)]

I have the same problem with Ubuntu 10.04 but not with other clients that are 10.10.

[Naresh(OpenERP) (nch-openerp)]

hello Anders Wallenquist,

I am using ubuntu 10.04 with gtk 2.20 and pygtk 2.17 and I cannot reproduce this .

Can you provide more information with the package details and also ass to what action you performed to raise such error.

Thanks,

[Aamir Riaz (riaz-aamir)]

Hello All, my problem has been resolved, i refresh my Ubuntu 10.04 installation and now OpenERP GTK Client is running smoothly, i am not sure what was the real problem ? Thanks anyway.

[Anders Wallenquist (aw)]

I have the problem on a newley installed Ubuntu 10.10

openerp-client_6.0.1-0_all.deb (from openerp.com dowload)

libgtk2.0-0 2.22.0-0ubuntu1

The package openerp-client have dependencies for these packages (if other are needed we should add this to the dependency list in the package):

Depends: python, python-glade2, python-gtk2, python-pydot, python-tz, python-hippocanvas, python-matplotlib

python 2.6.6-2ubuntu2
python-glade2 2.21.0-0ubuntu1
python-gtk2 2.21.0-0ubuntu1
python-pydot 1.0.2-1
python-tz 2010b-1
python-hippocanvas 0.3.0-3
python-matplotlib 0.99.3-1ubuntu1

The package search are a good utility to check what packages are installed in a certain release of ubuntu:
http://packages.ubuntu.com/search?keywords=python-gtk2

Recommends: python-openssl, openoffice.org-writer, evince | pdf-viewer

I suggest this instead:

Recommends: python-openssl, openoffice.org-writer | libreoffice-write, evince | pdf-viewer

From Natty LibreOffice are the default office suite

I attache a diff list of packages between one working Ubuntu 10.10 and one not

dpkg --get-selections (on working 10.10 and not working 10.10)

[Anders Wallenquist (aw)]

aw@lian:~$ openerp-client
** Message: pygobject_register_sinkfunc is deprecated (HippoCanvasBox)
Fatal Python error: GC object already tracked
Avbruten (SIGABRT)
aw@lian:~$

I got the first messate " pygobject_register_sinkfunc is deprecated (HippoCanvasBox)" when entering sale.order tree-view and the fatal error when entering the form-view for the same model.

This is reproducible on almost every form-view

Aamir Riaz: What did you do to "refresh" your installation?

To me it looks like if I install 10.04 and then upgrade it to 10.10 it works, but if I do a 10.10 install from scratch the openerp-client breaks...

[Aamir Riaz (riaz-aamir)]

Simply, I re-installed my Ubuntu 10.04, then got all of its updates from
"Update-Manager", after that I got the latest source-code of OpenERP (Server
& Client) and then I followed the instructions exactly written in the
"INSTALL" file.

P.S. This file is located in /openerp-server-6.0.1/doc for server
installation and /openerp-client-6.0.1/doc for gtk-cleint installation.

Hello,

On the base of comment # 10, I am closing this bug.

Thank you All.

[lodopidolo (dir-launchpad)]

No more. The client starts, but in certains moments it crash.

What's the problem?

Thanks.

[Amit Parik (amit-parik)]

Hello,

As per the comment#4 of Alan on lp:905738 which is gives 's solution and also described that problem comes due to orca.

So I am closing this issue.

Thanks!

[Alan Bell (alanbell)]

no, not agreeing that at all. Orca is there as an accessibility tool to allow blind and partially sighted users to access their desktop, and this should include OpenERP. OpenERP is triggering some conflict with at-spi that severely crashes python itself, but "don't use openERP if you are blind" is not a fix to the problem.

[Alan Bell (alanbell)]

If you are sighted and are encountering this problem in Ubuntu then you can go to system settings, universal access and on the seeing tab turn off the screen reader then log out and back in again. This turns off desktop accessibility, having orca not running isn't the issue specifically, it is at-spi being on that triggers it - orca just uses at-spi to get information from applications about what they are displaying.
