Comment 1

[Jonathan Kew [:jfkthame]]

This stack points to the support code for harfbuzz integration in gfx, rather than harfbuzz itself. However, I'm suspicious that the real cause is some other kind of brokenness on a single user's installation. From the crash times and install age figures, it looks like all 6 crashes that I see at the moment come from a single system.

It seems that we no longer crash here.
