Nothing routine running TDE on a Jessie/Sid system, it is compiled for 
Wheezy, just because you were lucky to get it working ...updates to 
Jessie are unpredictable as far as TDE is concerned.

Also the TDE mirrors are syncing right now, when finished you will not 
need slaveks repo's anymore.

 "apt-cache policy kde-core-trinity"
