[Mrtrix-discussion] mrview segmentation fault

[Corina Melzer]

Hi Donald.

Thanks for this very helpful hint. I just updated freetype version from v2.5.1_0 to v2.5.1_1 and now everything works fine.

Thank you very much.

That's very unlikely to be due to MRtrix per se, but with some bug in the GTK or FreeType libraries installed on your system. My suggestion would be to try different versions of these libraries.
