Hi so I am running Linux Fedora 29 and since updating from Fedora 28 I have noticed my Chimera installation has stopped working - the icon does not open the program. And when I try to run from the command line I get the code below, which I gather is an issue with python importing a module:

Traceback (most recent call last):
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/share/__main__.py", line 69, in <module>
    value = chimeraInit.init(sys.argv)
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/share/chimeraInit.py", line 628, in init
    import chimera
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/share/chimera/__init__.py", line 2758, in <module>
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/share/SimpleSession/__init__.py", line 14, in <module>
    from save import saveSession, sessionID, noAutoRestore, autoRestorable, \
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/share/SimpleSession/save.py", line 13, in <module>
    from chimera import replyobj, selection, SessionPDBio, version
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/share/chimera/replyobj.py", line 24, in <module>
    import Tkinter
  File "/home/gwenny/.local/UCSF-Chimera64-1.12/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: /usr/lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

Any help would be appreciated.
Thanks and best wishes,
