Apple Mail: missing plug-in

I keep getting "missing plug-in" messages from Apple Mail in emails that contain actually JPEGs or other common attachments. I don't know when this exactly started (could be installation of 10.8.3 update or a security update). This "feature" occurs only on my Mac Pro. On my Macbook Pro all works fine with the same configuration.

Faulty system: Mac Pro Early 2008, Mac OS Mountain Lion 10.8.3, latest Apple Mail.

Working system: MacBook Pro 15" Retina Mid 2012, Mac OS Mountain Lion 10.8.3, latest Apple Mail.

I scanned this forum and the usual Google hits for help. I tried the following already:

repaired permissions, checked disk
all system & software updates done
Java preferences "restored to default", Java preferences deleted
repaired mailboxes
applied combo 10.8.3 updater
applied iTunes 10.2 combo installer
checked all configurations, nothing unusual.
sent an email with photo attachment via iPhoto
danced in circles @ midnight & full moon

Nothing worked so far. Any useful idea. This keeps annoying me!

Kind Regards

Frank

Nothing works for me. 10.9 Mail shows 'missing plug-in' when I attach jpgs and if I send it out it arrives as a tiny version of the original. Seems Apple ought to fix this, no? Quit and restart? This is a joke, right?

This worked like a charm! Thanks for sharing.

I'm having the same issue running 10.8.5, only pic(s) appear at the end of the incoming email. Any suggestions?

Restoring Java defaults solved this issue for me.

Applications > Utilities > Java Preferences

Under the "General" tab, make sure both Java SE 6 are selected and hit "Restore Defaults"

Worked like a charm without the crazy extended processes I've seen others describe.
