problem in porting QString::at(index)

FYI, I managed to get KMail in trunk to receive mail from a local account
(w/o lock file) into maildir folders. If you manage to bring KMail up on a
KDE 4 desktop, you can at least read local mail. :)
I've found a problem in a changed semantic of QString::at(0) which seemed
to return '\0' in Qt3 for an empty string. Now we run into an assertion
for 0 <= i < size() although the Qt4 docu says about QString::size(), that
at position size() of a QString there is ever placed a '\0'. So you could
access it zero-terminated by data() etc. etc.
We just can't access that zero-termination by at() any longer.
We can of course work around that by checking the size before the index
access. But this makes the code a bit longer. The question if whether the
new sematic is intended by Qt.
for the critcal code.
