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

[Bill Gee]

Hello everyone -

I installed therion 5.3.16 a week ago but never did anything more than verify 
it would start.  Now I need to do some work on a map.  In xtherion - Whenever 
I try to open either a th or th2 file (text editor or map editor windows), it 
throws an error.  I took a screen shot and attached to this message.

The error comes up as soon as I click on the File-Open icon.  It never 
presents a file chooser dialog.

The cave will compile correctly.  The thconfig file opens without error.  This 
all worked in 5.3.15.

The system is 64-bit Fedora 21.

Any ideas?

Thanks - Bill Gee
