[ROOT] error in <TTF::SetTextFont> with version 3.05.07 and 3.10 of root

	Dear Root People,

I have a problem while compiling a program with new versions of root. It
works well with older version (v3.03/06).
Here is the error I have,

	Error in <TTF::SetTextFont>: font file arialbd.ttf not found in path
	Error in <TTF::SetTextSize>: current font index out of bounds

a lot of times, and this happened at a simple line of my program:
		hist1->Draw();

If I just comment this line but define the histogram in the same way, it
works well.

	I hope I am giving enough information, I put my 'detailed' programs here
below in case you need it.


		Thanks a lot for your help,

			Best regards,

					Anne-Marie.



My program around the bug is: ("........" means a lot of things done with
nothing to do with the problem)
