Wow, you exceeded the number of packages this APT is capable of. Problem with MergeList /var/lib/dpkg/status. The package lists or status file could not be parsed or opened

Hi, I get this error very often. First time it was on 3GS (I had approximately 10 repos added), Cydia wasn’t working, I tried deleting some cache files in the showed folder and eventually destroyed the whole app. After some time I reinstalled everything, it was fine till today. The same happened with my iPad Mini I bought today. I only added 3 repos to both of them. This time I deleted one of them and everything works fine, but I still want to add more repos. What should I do? This is how it looks: http://i.imgur.com/k2LEpYY.jpg
