[Zope] Part-time tracebacks

[Phil Harris]

Hi all,

I have a problem.

I have a folder that contains file objects that contain text/xml.  (I know I
could have used XMLDocuments, but I found them too slow).

These documents are being rendered to html via xsl in an external method,
using a java based xsl processor and this is pretty much working well, but.

Some of the documents cause the error below, any ideas?

Error Type: TypeError
Error Value: argument 1: expected read-only character buffer,
ImplicitAcquirerWrapper found

Traceback (innermost last):
  File C:\PROGRA~1\zope\lib\python\ZPublisher\Publish.py, line 214, in

I am using Zope 2.1.0 on NT.

Any help would be greatly appreciated.


TIA
