Hi Marcus, I've had a crash while dearchiving core text objects, though not this particular case with archiving.
Obviously the object that's crashing is a UIFont used by the NSAttributedString. One of its properties - by the look of it the font ascent - triggers the underlying C++ code to calculate the metrics of the font. It's possible that the font is corrupt and the code just isn't ready to handle the possibility. Can you try with a different font and see if the problem goes away? It's probably worth filing a radar because I would say that archiving arbitrary fonts either needs to work robustly or fail cleanly. When I filed a radar on a similar kind of fault recently it got notified as a dupe, so some of these issues are known. --Graham On 20 Jan 2014, at 5:54 am, Markus Spoettl <ms_li...@shiftoption.com> wrote: > I got a crash log from a user that's mildly puzzling.
