crashes with SIGSEGV in do_rebuild() when running under valgrind

Binary package hint: evolution

This crash was shown twice while I was running compiz from valgrind to try to catch other errors.
I hadn't started evolution manually, but may have passed the mouse cursor over the indicators in the panel.
