[Bug-XBoard] Xboard-hgbranch-master: Texture on the fly loading bug

[Joshua Pettus]

Hi, I haven’t yet narrowed down which commit broke this, but with a build from the current hgbranch code, xboard crashes out whenever I change the board textures (or pieces) while xboard is already open.  Texture changes were done through the board menu.

It doesn’t crash with the textures loaded in on launch which is strange:

Assertion failed: (CAIRO_REFERENCE_COUNT_HAS_REFERENCE (&surface->ref_count)), function cairo_surface_destroy, file cairo-surface.c, line 953.

/Applications/Chess/Xboard/XBoard.app/Contents/MacOS/XBoard: line 69: 84183 Abort trap: 6 

Regards,
