Comment 10 for bug 1448407

Interesting but not further fruitful.

gvfs-info 20060627\ One\ Codes.ods (just one sample)

gives these attributes:
...
display name: 20060627 One Codes.ods
...
type: regular
...
attributes:
  standard::type: 1
  standard::name: 20060627 One Codes.ods
...
  standard::icon: application-vnd.oasis.opendocument.spreadsheet, x-office-spreadsheet
  standard::content-type: application/vnd.oasis.opendocument.spreadsheet
  standard::fast-content-type: application/vnd.oasis.opendocument.spreadsheet
...
  standard::symbolic-icon: application-vnd.oasis.opendocument.spreadsheet-symbolic, x-office-spreadsheet-symbolic, application-vnd.oasis.opendocument.spreadsheet, x-office-spreadsheet
...

gvfs-mime --query 20060627\ One\ Codes.ods
No default applications for '20060627 One Codes.ods' (Hey? right clicking provides open with LibreOffice Calc!!!)

Searched a bit more, found a reference to ~/.config/mimeapps.list and ~/.local/share/applications/mimeapps.list. They differ in content but provide overlapping sections and mime types.

Strange that the application/vnd.oasis.opendocument.spreadsheet is missing from both files.

I compared these files to the ones I had with 14.10 (where the icons were displayed correctly): No differences here.

Any suggestions?
