Looks like as if the Habari format functions which should have been called when initializing the theme do NOT work.
Esp. the filter autop is getting on my nerves (for not working).

Thus I had to introduce some bloody old-school procedural functions, including one called nl2p, which is a pretty, tidied up rip-off of the wordpress break-to-paragraphs-conversion out of WP 2.0.

Before that, I got my posts always and ever fucked up. Some breaks showed, other not. After I tried to output it in a different way, suddenly lotsa line-breaks appeared on places where there shouldnt have been any.

Thanks to my quick'n'dirty hack, it works for now. But I'm not going to stick to that function .. I dont have given up yet! ;)
