Bug#873792: qjackctl will not start at all

[Ed Peguillan III]

Package: qjackctl
Version: 0.4.5-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?
   I use jackd to facilitate realtime audio according to my limits.conf
   for some software called Pianoteq. In the last update, I tried to run
   qjackctl and received the following error:

   qjackctl: symbol lookup error:
   /usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5: undefined symbol:
   FT_Property_Set
    
   I am unable to start qjackctl

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   I do not think I intentionally installed any extra packages that stops qjackctl from launching properly.

   * What was the outcome of this action?
   qjackctl does not launch

   * What outcome did you expect instead?
   qjackctl launches normally
