Problem with imported logfile data (no replies)

Hello,

I´m new to piwik and this forum. I used the search function but without success.
So here is my problem:
I used the python import script to import the apache logfile and that worked.
But when i take a look at the visitor-log there is something wrong with the actions.
What they look like:
http://www.mysite.dehttp//www.mysite.de/wasser-sparen.html
What it should look like:
http://www.mysite.de/wasser-sparen.html

I have no idea why piwik puts the default URL in front of the action and why the ":" after the second "http" is missing.

Someone knows the problem?

Regards,

Klaus
