Can't send document as Opera Mail attachment from LibreOffice
I use Opera 12.02 as a mail client and LibreOffice 3.4.5 as my office suite, running Linux Mint Debian Edition 201204. LibreOffice has a "send document as email" command. Searching the web, I see it works fine with some other mail clients (Thunderbird, etc.). But when I try it, I get the error message:
"LibreOffice was unable to find a working e-mail configuration. Please save this document locally instead and attach it from within your e-mail client."
The relevant configuration appears to be found in LibreOffice at Tools - Options - Internet - Email. I've tried "opera", "/usr/bin/opera", and "/usr/bin/opera --remote 'openComposer(new-window)'" (all without the double quotes). All of the above work from the terminal, and the latter (from man opera) opens a new message composition window, but none make LibreOffice's error go away.
Searching the web, this forum, and LibreOffice's documentation turns up nothing relevant.
I'm out of ideas. Does anyone know how to make LibreOffice play nicely with Opera Mail?
