Google shows this error referenced on some Thunderbird bug, but it's not clear to me how they resolve it.
Here is my issue:
I have vorbis file:
xdg-mime query filetype "my-file1.ogg"
xdg-mime query filetype "my-file2.oga"
I tried to add a key in gconf with gconftool-2 using above mime-type (
x-vorbis+ogg) and I got this error:
`+' is an invalid character in key/directory names
If I ignore reported mime-type by xdg-mime and instead use simple mime-type for vorbis -
ogg, then the key works only for files with extension ".oga" but not with more common extension ".ogg"
What to do? Is it possible to escape 'plus' sign in reported vorbis mime-type when passing to gconftool-2? Is this but in gconftool-2?
