Hello all,
I have a Cocoa project that runs fine on my PPC Mac OS X 10.4.10
machine, but
crashes on my father‘s Intel Mac OS X 10.4.6 machine. More details :
1) On the Intel I get the error message
2007-09-08 19:00:35.698 Schreiben[1599] *** -[NSKeyedUnarchiver
decodeObjectForKey:]: cannot decode object of class (GGValue)
and no error message at all on the PPC.
2) The best I achieved in bug tracking is that the crash occurs during
the computation of
[NSDocumentController openUntitledDocumentAndDisplay: error:]
3) GGValue is a class that existed in earlier forms of the
project, but not in the current version. In fact, if I use the
"Find in Project" functionality in Xcode and look for occurrences
of the string "GGValue", the answer is no match at all.
4) One would then expect that this problem stems from old data
that are misread by the new version of the app. However, this is
contradicted
by point 2), which shows that the crash occurs when a completely new,
untitled
document instance is created.
Any ideas ?
TIA,
Ewan
