Redmine

Note:
This duplicates my post to - https://github.com/leovitch/redmine_importer/issues/36

I love the Importer plug-in: http://www.redmine.org/plugins/importer
Importing new issues works great!!

When I try to update any existing issues, I get the error message below and the log entry below.

I think I'm using the latest plug-in version:

Issue Importer Issue import plugin for Redmine.
Martin Liu / Leo Hourvitz 1.0 c65c222....

The plugin folder is named 'redmine_importer'.

I'm running: Redmine 1.2.1.stable (MySQL)

I followed the directions in the Wiki and Sample file - https://github.com/leovitch/redmine_importer/wiki

I tried all sorts of variations of the import csv file, made sure it is UTF8, etc., but I get the same error above.

I tried removing all other plugins, but I get the same error above.

I tried updating to the latest FasterCSV (v1.5.5), but I get the same error above.

Please help!!
