--- Comment #3 from Matěj Laitl <matej at laitl.cz> ---
I have the same problem. I have Nepomuk enabled and enabled for indexing
e-mails. Starting other pim-related applications (akonadiconsole) also hangs.
Clicking the "Details..." in the "Desktop Search - KDE Control Module" to
troubleshoot freezes the dialog.

It seems to hang on some DBUS call. How do I debug where's the problem? (other
app didn't reply?)
