UITextField crashes on type

I have a UITextField initted from a xib file. For some reason, it crashes on the second key I type ( or the first number, for some reason ). EDIT: forgot to mention, it crashes with an EXC_BAD_ACCESS. NSZombieEnabled=YES doesn't change anything. there's no code to show, as it's only the xib file. This is the backtrack:

Does anybody know what can cause this/how to fix it?

Tnx in advance!

You need to provide more information. Is that the only field crashing your app? Has it always behaved like this?

That said, it looks like it's the autocompletion that's crashing on you. Try disabling autocomplete for that field (IIRC, there's an option for that in Interface Builder).
