Redmine

While submitting a new issue by email /with rdm-mailhandler.rb script/, some files are ignored /not attached to issue/.

It's happend with following file names:
- "Jakie zasady powinna przyjąć gmina, aby nie naruszać zasad konkurencji 12 grudnia 07 (nr 241).doc"
- "Kto odpowiada za wypadek, który miał miejsce na terenie szkoły 6 maja 09 (nr 87).doc"

The files content is not important, only files name is significant.

This problem not occurs, while I attached the same files for issue, but with "New issue" form http://www.redmine.org/projects/redmine/issues/new
