Mobile Sync, Part Two

I have an older IBM Thinkpad (a T42p) laptop with Ubuntu Studio installed. In version 9.10, syncevolution worked like a charm. All I had to do was to install, setup the N900 and sync, no problems whatsoever. Then I got brave and upgraded the laptop to Ubuntu 10.04 and syncevolution to the latest version.

Fail to sync.

And mind you, it doesn't tell me what's wrong, it just fails. I've tried installing older syncevolution packages, resetting bluetooth stuff, sacrificing my firstborn... nothing helps!

If you know what's wrong, please let me know.
