Hello Steve,
Alas yes, the Perl debugger is buggy.
It can't handle lvalue subs assignment.=20
It means that whenever you assign something to "this" or to a Qt::attribu=
te,=20
it will hold "undef" under the debugger.
See BR #17663: http://bugs6.perl.org/rt2/Ticket/Display.html?id=3D17663

There's not much we can do except finding the bug (tough luck).
So that's why I added debugging channels in the first place : to give cor=
rect=20
debugging feedback while the debugger is broken.

perl -MQt::debug=3Dall YourProg.pl    is your only friend.=20
