Bug#898960: Same issue with MATLAB R2017a

[Sylvain Chevillard]

Hi,

I get exactly the same issue with MATLAB R2017a under testing.

As mentioned earlier, the issue is with libpangoft2-1.0-0_1.42.1-1 and 
downgrading it to libpangoft2-1.0-0_1.40.5-1 fixes the issue.

Way to reproduce: inside MATLAB, write a keyword and press F1 to toggle 
the help window. Shortly after the window appears (and before the 
contents of the help appears) MATLAB crashes with the following message.

Hope it helps.

Best regards,

Sylvain Chevillard
