[Kde-perl] Memory fault when inserting QTableItem into QTable

[Oliver Kreuer]

Hello,

first of all I have to apologize that I couldn't spend time until now to 
test the patches provided by Richard.

I've tried patch perlqtdispose_0.2.patch (see thread "Freeing memory 
used by QTableItem) and it works fine in my testscripts. I didn't try 
patch perlqtdispose_0.3.patch because Richard wrote that he's going off 
the idea a bit.

So for me this patch (0.2) solves my problem. As far as I understood the 
  ongoing conversation after Richards 0.2er patch this patch isn't as 
"stable" as one could wish.
Therefore I wonder if there will be a "final" solution to this problem 
in a next or newer version of Perl/Qt?

Thanks for your help.
Oliver
