The Thunderbird indicator extension can spam the bus when moving large number of emails

[David Barth]

I've recently moved ~10.000 emails into a new folder. I have a folder of 90.000 emails for example.

During the move operation the extension signaled every single change to the messaging indicator. The result of that was essentially an unusable system during 5 minutes, as both dbus-daemon and the messaging service were using ~100% of the CPU.
