hello again
as the title says this code can lead to crashes:
[[NSUserDefaults standardUserDefaults] setObject:0 forKey:@"bla"];
i've attached a small sample. choosing the "choose me" in the popup button
opens a sheet. clicking the close button in the sheet makes the faulty user
defaults call.
trying to open the sheet again terminates the app with a segfault. weirdly
again i can't get a backtrace from gdb, because everything just freezes and i
have to kill -9 the process from a virtual terminal.
weirdly the same call additionally causes an X11 error "X-Windows error -
RenderBadPicture (invalid Picture parameter)" in my full app but not in this
sample - but i guess something just goes horribly wrong and if this bug is
fixed the X11 error will vanish too.
btw sorry i just now realized that is probably a bad idea to submit minimal
samples that contain "@synthesize". now in pure obj-c 1.0 ;-)
