repo.or.cz problem with blame/history/raw links

Hi,

blame/history/raw links seems to be broken on repo.or.cz [1]
They have ARRAY(0x85bfb90) instead of the project name/path in the link

so the broken link looks like:
http://repo.or.cz/w/ARRAY(0x85bfb90)?a=blob_plain...

According to  Jakub Narebski this does not happen on unmodified gitweb.
Since i have little to no idea about gitweb maybe somebody else can have a 
look at it?

Greetings
Peter
