[BUG] TreeModel->move_before() eats all cpu time

[Thierry Vignaud <tvignaud mandrakesoft com>]

while porting drakperm (from drakxtools), i saw that
Gtk2::TreeModel->move_after() works smoothly whereas move_before()
makes the Gtk2::TreeModel->program going bad (that is eating all the
cpu time ...)

if you want to test it:

- check out the drakx{installer,tools} repositery:

export CVS_RSH=ssh
export CVSROOT=
cvs -z3 -d :ext:anoncvs cvs mandrakesoft com:/cooker cogi/perl-install


- apply the following patch to switch from inline to xs gtk2-perl:

Attachment: xs3.diff.bz2
Description: Binary data

- type "for i in *.pm */*pm; mkdir -p /usr/lib/libDrakX/$(dirname $i);
  cp -a $i /usr/lib/libDrakX/$i; done"

- run ./standalone/drakperm
