Front end crash on Export in 10.2 on OS X macbook air 6,2

Question

When trying to create a PDF (export, print-save as, save image as) fronted crashes. With both OS X Mavericks and El Capitan

My machine is: Model: MacBookAir6,2, BootROM MBA61.0099.B19, 2 processors, Intel Core i7, 1.7 GHz, 8 GB, SMC 2.13f15

But with OS X El Capitan and the same mathematica 10.2 on a mac mini 6,2 works all fine.

The error log begins with 0 libpangocairo-1.0.0.dylib 0x00ed0f56 run_iterator_get_cgglyph + 22
