Hi.

I did not find any crash situation or bug to fix. I just tried to understand what was the root cause of the "missing logger" message, someone was complaining about. Which I described above (always assuming it is the correct one ...).

Bye

What you see there is the result of a refactoring of the very ancient
mode trunk/compat used; it just dumped to file without timestamp and
else. Since core on the other hand had/has a very clean implementation
using the logging module, I started a transition from "just dump to
file" to using the logging module as core does in order to finally
converge with compat against core.

So you are charging an open door - that was the reason why I asked for
"can you give me more details please" e.g. a description and a
traceback of an actual crash situation? That would give me a point to
start on and fix this concrete bug as well as improve the situation
overall.

Of course you can also implement your own changes - I would be happy
to review them - but please keep in mind you have to be very careful
not to break things here. E.g. a message that no logger is defined is
annoying indeed, but does not break the code to run...
