reproducible core dump in Qt::Table

System: Debian/x86

Package versions:

ii  libperl5.8     5.8.3-2        Shared Perl library.
ii  libqt-perl     3.008-1        Perl bindings for the Qt library

The simplest way to reproduce this is to use pqtsh.  When I run the
following commands:

    use Qt::attributes qw(table);
    table = Qt::Table();
    table->show;
    table->setNumRows(1);
    table->setNumCols(1);
    table->setText(0,0,"hello");
    table->removeRow(0);

the final command causes a segmentation fault.  valgrind strongly
indicates that this is a double-free bug (logs appended).
Interestingly, if I keep running (which is possible only under
valgrind), I don't see the problem again.

Is there any other way for me to remove rows from a table using
PerlQt?

                Marc
