pysqlite2.dbapi2.ProgrammingError: library routine called out of sequence

Pysqlite-list,

I am writing an application which makes use of Twisted <http:// 
twistedmatrix.com/trac/> and Divmod Axiom <http://divmod.org/trac/ 
wiki/DivmodAxiom>, which in turn makes use of pysqlite 2.0.7 and  
sqlite 3.3.6.

I have made an application bundle (for the Mac) using py2app, which  
runs fine on my mac and other macs on my network, but for some reason  
I get the following traceback when I (well, a user) tries to run this  
any one of several macs on their network. I have tried various Macs  
and network connections (cable, dialup) to try and rule out a single  
mac or the network as the problem.

pysqlite2.dbapi2.ProgrammingError: library routine called out of  
sequence

The line it is referring to in my source  (File "salespipeline/model/ 
remote.pyc", line 89, in setCopyableState) is this:

         self.db = Store()

This is how you create an Axiom in-memory SQLlite database, and  
should work fine.

So... it dies while trying to make an in-memory store. I'm not sure  
the problem is with my code, or something to do with how I've used  
py2app, Axiom or pysqlite. I've already send a similar mail to the  
Divmod mailing list..

I believe it may be related to the problems Skip is having here:
http://mail.python.org/pipermail/python-dev/2006-October/069504.html

I will try and reproduce his problems tomorrow.

Thanks!

Robert
