Bug#623431: patch

[D Haley]

Hello,

I sent some patches to the upstream maintainer a while ago, tentatively looking at this problem.

I have since been able to reproduce your problem -- it seems to occur in a mixed locale session.  After applying the patches that were applied to mathgl (here), and updating my local repo, the segfault goes away.

http://mathgl.svn.sourceforge.net/viewvc/mathgl/mathgl-1x/mgl/mgl_font.cpp?r1=175&r2=181&pathrev=181

Let me know if this works for you.
