[mod_python] strange import behaviour out of the blue

What version of mod_python are you using? You didn't by chance upgrade
your mod_python version lately, for example to 3.2 beta?

Also, are you using mod_python.publisher or are you using your own top
level handler? Are you using module reloading on the module the import
occurs in? This could be explicitly using apache.import_module() or by
virtue of PythonAutoReload defaulting to On or being set explicitly On.

There are a lot of known issues with module loading/reloading in
mod_python. Version 3.2 starts to remedy some of these issues, but
even so those changes are really an interim fix until 3.3 tries to fix
all problems properly in some way.
