I just did a configuration file with dialplan and a record like you
showed and it started ok. My log messages are pasted next:

Is it a fresh installation or an update over an older installation? If
is the second, can you doublecheck to see if all modules were compiled
and installed at the same time and are no longer older versions?
Also, what is your operating system and architecture type?
I tried with both master/devel and 3.1 branches.
Thanks,
Daniel
