Crash on macOS with some custom fonts installed

[Xisco Fauli]

Hello,

it would be hard to reproduce it / investigate it if the font is not
mentioned.

Could you please ask the user to report the bug in Bugzilla <
https://bugs.documentfoundation.org/enter_bug.cgi?product=LibreOffice&format=guided
> providing all the information required in order to reproduce the issue ?

Thanks
