micsmc and QGtkStyle problem

[j0e]

Recently, after some updates no doubt, when I try to start up micsmc, it briefly does, but then quickly issues this error and closes:

QGtkStyle was unable to detect the current GTK+ theme.
terminate called after throwing an instance of 'mic_exception'
  what():  std::exception

micctrl --config gives

I'm running CentOS Linux release 7.3.1611,  I assume this is a linux problem I need to solve, but it does mention the mic_exception.  Although I have frozen kernel updates, other system components are updated from time to time.  It would be nice if the MPSS would allow kernel updates without have to reinstall MPSS.

Thanks for any help?
