It seems this commit make things crash here:
http://svn.gnome.org/viewvc/pygoocanvas?view=revision&revision=229

Here's the stack trace when simply running 'python -c "import goocanvas"':

Reverting this svn commit makes it work fine for me.
Comment 1 Gian Mario Tagliaretti 2009-05-10 09:06:55 UTC 
Vincent I couldn't reproduce this bug, could you try with the latest pygobject and pygoocanvas?
Comment 2 Vincent Untz 2009-05-17 23:24:58 UTC 
Still crashes here with pygobject 2.17.0 and pygoocanvas 0.14.1. And the patch still fixes it :-)
Comment 3 Gian Mario Tagliaretti 2009-06-09 22:15:41 UTC 
cc'ing Armin to have his opinion
Comment 4 Armin Burgmeier 2009-06-10 18:02:38 UTC 
I'm sorry, I can't reproduce the problem either. Hm. The only thing I can think of is that maybe you have two different python versions installed, and it detects and therefore links against the "wrong" one?
Comment 5 Vincent Untz 2009-06-10 18:20:38 UTC 
No, there's only python 2.6. Weird :/
Comment 6 Gian Mario Tagliaretti 2009-06-10 20:40:35 UTC 
uhm... Vincent what version of pycairo are you using?
Comment 7 Vincent Untz 2009-06-10 20:48:14 UTC 
(In reply to comment #6)
> uhm... Vincent what version of pycairo are you using?

1.8.4.
Comment 8 Gian Mario Tagliaretti 2009-06-10 20:56:24 UTC 
argh... this is the only release which works well with the latest pygoocanvas :)

next question on the list x86_32 or x86_64?
Comment 9 Vincent Untz 2009-06-10 21:38:59 UTC 
32 bits here :-)

dbx backtrace
Comment 11 megamic 2011-01-24 01:07:14 UTC 
I believe I am seeing a similar bug on Solaris, compiling as a 64-bit module. Using the following versions (all compiled from source as 64-bit):
Python:2.7.1
PyCairo:1.8.10
PyGobject:2.27.0
PyGtk:2.22.0
PyGooCanvas:0.14.1

The backtrace I get from dbx is attached.
  
If this is unrelated, I might submit a new issue report.
Comment 12 megamic 2011-01-24 02:41:32 UTC 
I managed to work around this bug by stopping pygoocanvas from statically linking against libpython. Removed -lpython2.7 and -no-undefined from makefile. Rebuilt and everything seems to work ok =)
Comment 13 André Klapper 2014-08-02 12:24:16 UTC 
The last Pygoocanvas code changes took place in 2010:
https://git.gnome.org/browse/archive/pygoocanvas/log/

This project is not under active development anymore.

This project has been recently archived in GNOME Git.

It is currently unlikely that there will be any further active development.

Closing this report as WONTFIX as part of Bugzilla Housekeeping to reflect reality. Please feel free to reopen this bug report in the future if anyone takes the responsibility for active development again.
