CvPcb starts very late in Debian Jessy

I just installed Kicad 4.0.1 build 6403. Because of an error during the installation i did this : Error by building BZR 6362 on Debian Jessie . Now it is working but when I try to start Cvpcb in EEschema nothing is happening and all Kicad Windows only show a Grey screen. After 10 Minutes Cvpcb starts . Can anyone here tell me why this needs a so long time and how I can fix this Problem .

I’m using, apart from one self made Library, the github Library’s.
