Hey,

Today, I have deleted my old Bitshares client and compiled the new version 0.4.27.2 with my ubuntu 14.04 machine. Unfortunately, now the client crashes each time I am trying to start it. The console gives me the following error messasge

~/bitshares/programs/qt_wallet/bin$ ./BitShares

 It would be great if someone could explain me what exactly is happening and how I can resolve this problem.

Thank you
