Is there any way to force Thunderbird into opening the attachments with the associated application?

Or at least to open the association dialogue instead of the file open dialogue?

It's really driving me nuts. The easiest way to open the attachments is to save them to disk and open them from the file manager.

@sr_ Nope. No useful information there. The extensions are completely useless. I want to open the attachments with the associated apps not to manually create a duplicate of associations. – Let_Me_Be Oct 18 '11 at 14:38
Sorry, I was a little fast with this link. I suspect it should be possible to tell Thunderbird to use kde-open or xdg-open, but I can't find anything about it... – sr_ Oct 18 '11 at 14:50
@sr_ Well yes, that would be a great solution :) But it doesn't seem to be possible. – Let_Me_Be Oct 18 '11 at 14:55
This probably is bad news, although these bug reports refer to Firefox but there might be little hope to have Thunderbird fixed if Firefox isn't, too. – sr_ Oct 18 '11 at 15:04

Security holes to the rescue!

Apparently, both Thunderbird and Firefox (can be configured to) use /etc/mailcap which can in turn be used to call xdg-open, see this bug report (referring to this one including a (rogue) mailcap example), especially comment #2 on how to make it (more) secure.
