[Therion] Therion 5.3.16 - Error opening th and th2 files

[Bill Gee]

Update:  This is definitely a problem with Tcl/TK and maybe tkimg.  I found a 
computer with Fedora 21 and Therion 5.3.13 still installed.  This computer 
shows the same problem.

Therion obviously has not changed, but the system is patched up to current.  
That means it is not a problem in Therion.  Something must have happened to 
the other subsystems.
