Boa noite
Realmente eu encontrei algo sobre o assunto, mas não tenho os conhecimentos técnicos para os utlizar.
Se alguém me ajudar eu agradeço e deixo aqui o tutorial.
"F-spot uses evolution by default. If you try to use Thunderbird, the default in Xubuntu, you'll get an error.
Launch gconf-editor via the terminal. (If it's not installed, then sudo aptitude install gconf-editor.)
In the gconf-editor gui, select Desktop, Gnome, url-handlers, mailto. Then change the command field to mozilla-thunderbird %s.
This lets f-spot know to use thunderbird to send emails with images.
Then another maddening error kept popping up. I could only send about half of the emails with images from f-spot. The answer to this problem was on the f-spot site here:
http://f-spot.org/User_Guide/ShareThe problem was f-spot and thunderbird were only giving me 30 seconds to compose the message and hit the send button. Any longer and the images were deleted from the tmp directory.
Here's the solution from the f-spot site:
"If you're sending resized pictures, F-Spot will keep the modified versions somewhere in the
/tmp directory for 30 seconds. It's not an issue with evolution, which makes it's own local copy of the
attachments, but could be a bit shorter if you're using thunderbird. You can change the delay by editing
the gconf key /apps/f-spot/export/email/delete_timeout_seconds."
note: again, use gconf-editor to change the timeout_seconds value. it's a nice, easy gui editor.
I set it to about 2400 sec's."
Cumprimentos.
