The default configuration is, well, the default one. It's not guaranteed
to work, but do work in a lot of cases (i. e., when the remote is
supported by the kernel). Your statement that the official guidelines
doesn't work needs a citation, so to speak.
I note that you seemingly havn't used mode2 (?) This is the tool to
determine what kind of data the kernel makes available to lirc which in
the end determines what driver to use. This is described in the

These messages are actually misleading. I will look into this. That
said, they are not blocking.

Yes, but these are just "notice" messages. They can be ignored in this case.

Happy to hear that it works for you!

Actually, there shouldn't be anything incompatible between 0.9.4c and
0.10.0. This seems strange...

It's in the lircd.conf(4) manpage...

I definitely agree that the crash is a bug. If I could reproduce it (or
get a proper stacktrace) we might make a try to fix it. At least, we
could augment the message with the fact that irrecord might crash.
However, besides this the state of this bug is basically "wontfix".
