I get the following error when I use Edit This File when trying to edit a word document from Vibe

Error From Command (1)
'blah%20blah.docx' is not recognized as an internal or external command, operable program or bath file.

The catalina logs show no indication of what the problem could be and I have tried different browsers and java versions (6u38, 7u10) but still get the same results.

Any suggestions would be greatly appreciated.
