cannot open any open office file through Topshelf

[Neil Redgate]

I can open text and doc files through Topshelf by selecting "open" (or double-clicking) .
I cannot open any file created by open office - following error message -

The file 'file:///home/ndres/test.odt' could not be opened due to an error

the only way it works is by selecting "open folder" - this opens a nautilus windor of the folder where the particular file is located and I can double-click on the file icon and the file opens.

Would like to be able to select "open" for OOo files within Topshelf

Using Ubuntu 8.04 and have upgraded to Topshelf 0.3

many thanxs in advance
Neil
