Zotero plugin in Openoffice crashes by changing citation style

[Gerald]

Dear all,

I hope that here is the right place for a bug report. I tried to
describe the bug in the ticket system, but this did not work out for
some reason. Also, a few weeks ago, I placed the request in the Forum
"Troubleshooting", but did not receive any comment. Therefore, I hope
that you will be able to help me regarding this problem here in den
zotero-dev:

I have installed Zotero 1.0.1 and OpenOffice 2.3 on Windows XP, but
unfortunately it leads frequently to following error when I try to
change the citation style via the button "Set document preferences" in
the OpenOffice plugin:

When does this problem appear?
I open a new document and insert a citation. Then I want to change the
citation style via the button "Set document preferences". Sometimes
this works, but more often it doesn't. When it doesn't, the function
ends up in the OpenOffice Basic window showing the error message:
Basic Runtime Error: Exception Type: com.sun.star.uno.RuntimeException
Message: This object is invalid.
It stops in the line of the macro:
oRange.text.insertTextContent(oRange, oField, true)

The error is unpredictable, because sometimes it comes up when I
change the style the first time, sometimes changing styles works
several times without problems until it stops at the x-th time.

Is there a workaround for this issue? I hope that you can help me
regarding this problem.
Thank you very much
Gerald
