Description Eric Fikus 2012-10-05 16:45:07 UTC
The NSKeyedUnarchiver methods

    – initForReadingWithData:
    + unarchiveObjectWithData:
    + unarchiveObjectWithFile:

can commonly throw Objective-C exceptions that we can't handle on the main thread (eg when the unarchiver encounters unexpected data).

These are cases where it's common to wrap in a @try/@catch in Objective-C.  Is this something MT can handle, per http://stackoverflow.com/a/10549490?
Comment 1 Rolf Bjarne Kvinge [MSFT] 2012-10-06 04:19:13 UTC
Technically I believe it's possible, but we haven't looked into the details yet (I have vague plans to look into this some day, but there is nothing definite yet).
Comment 2 Rolf Bjarne Kvinge [MSFT] 2012-10-23 19:31:22 UTC
This has been fixed by doing custom marshalling of the exceptions for this particular class (NSKeyedUnarchiver).

The next release with this fix will be 6.0.6
