CocoaAgg error

Hi all,

When using CocoaAgg, I get this error message, Python hangs up, and no figure appears:

In [1]: from pylab import *

In [2]: A=zeros(10)

In [3]: plot(A)
Out[3]: [<matplotlib.lines.Line2D instance at 0x3fb48a0>]

In [4]: show()
2007-02-11 18:16:49.244 Python[1833] *** NSThread: ignoring exception '*** -[NSKeyedUnarchiver decodeObjectForKey:]: missing class information for object' that raised during delayed perform of target 0x400f950 and selector 'startWithBundle:'

I'm using Python 2.4.3 on OS X 10.4, PPC.

Thanks in advance for any help,
