Saving materials causes Wings to crash...

[kugelfang]

Wings frequently crashes when saving materials. It seems to happen if either the Outliner or Geometry Graph windows are displayed when the material is saved. No crash dump generated. Has happened on various model files or even when no object has been created. I can generally reproduce the error simply by saving (when either creating or editing) a material with either the Outliner or Geometry Graph windows open. But there are times when it does not crash. I've not been able to determine the exact trigger.

I'm using Wings 2.05 on Linux Mint 17.3 'Rosa' MATE 64-bit.
