Hi Andrew,

Didn't work for me. Here is my debugging info:

opus[~]$ uname -a

opus[~]$ lsb_release -a

I didn't have this directory. I had:
opus[~/.local/share]$ ll
total 20K
drwx------ 4 mishkin cta     4.0K 2009-09-09 17:21 Trash
drwxr-xr-x 2 mishkin cta     4.0K 2009-09-12 19:47 desktop-directories
drwxr-xr-x 3 mishkin mishkin 4.0K 2011-03-08 10:38 tracker
drwxr-xr-x 2 mishkin cta     4.0K 2011-05-05 13:46 applications


I created mime/application and put it in there.

opus[~/.local/share/mime/application]$ update-mime-database
/home/mishkin/.local/share/mime/
Directory '/home/mishkin/.local/share/mime/packages' does not exist!

I created mime/packages and it worked.

opus[~]$ xdg-mime query filetype data/cube.mnc
application/octet-stream

opus[~]$ file data/cube.mnc
data/cube.mnc: NetCDF Data Format data

I did the rest of the steps but was unable to bask in any glory.
