i experience the same probelms - very annoying on an old computer with little cpu power. i use
Release 12.04 (precise) 32-bit
Kernel Linux 3.2.0-39-generic-pae
GNOME 3.4.2
the high cpu is regularly after starting tb and goes on for quite a while (15 minutes +), it seems related to IMAP synchronization in a quite large mail account.
closing teh message pane did not reduce the cpu load.
