[snap] Issues associating attachments with default apps

[Francois Thirioux]

Detailed bug description here:
https://discourse.ubuntu.com/t/evolution-again-as-default-email-app-client/15457/65

Summary: link an attachment type to an application is possible but not as easy as it should. Issue only snap-related.

[Francois Thirioux (fthx)]

Note that I cannot open attachments in a compose window. Nothing happens (because confinement/apparmor, as far as I can see in Logs).
That's very annoying to check I send the good files.

The url of the attachment begins with file:///run/user/1000...
If I choose to send a file through Nautilus right-click/send-to, the url of file attached is usual one (location in home folder).

Please note that right-click works with TB snap only through nautilus-sendto update:

The issue you described in the comment is one we recently investigated and which is a bug in the xdg portal
https://github.com/flatpak/xdg-desktop-portal/issues/545

Is that what this bug is about (in case we should reassign) or if not could you be more specific in the description?

[Francois Thirioux (fthx)]

No it's only another attachment handling bug, but you showed it is not related.
The original bug stands still.

[Sebastien Bacher (seb128)]

Could you describe steps that shows the original issue? 'experience some oddities' isn't really a clear report

[Francois Thirioux (fthx)]

I agree but the link to Discourse given in bug description does show a typical part of this issue.
