--- Comment #5 from Eugene Savelov savelov@gmail.com --- same problem happens to me with wine 1.6, with russian locale.
winebrowser should convert filenames from windows encoding (here russian windows-1251) to linux system encoding (ru_RU.UTF-8 ) before passing them to gvfs-open
currently the error is displayed , and file is not opened gvfs-open: file:///home/eugene/.wine/dosdevices/c:/users/eugene/Local%20Settings/Application%20Data/SAMO%20Soft/Agency/Attachments/%3C%30%48%30.pdf: ошибка открытия адреса: Ошибка при получении информации о файле «/home/eugene/.wine/dosdevices/c:/users/eugene/Local Settings/Application Data/SAMO Soft/Agency/Attachments/<0H0.pdf»: Нет такого файла или каталога
