Bug#313207: libplot-perl: segfaults when trying to create plot for png, ps or gif

[Mattias Axelsson <mattias@barbanet.com>]

Package: libplot-perl
Version: 2.2.0-7
Severity: important


It fails to create plots when the selected device is ps, png or gif.
It is still able to create plots in an X window.

The following program reproduces the bug:

#!/usr/bin/perl -w
use Graphics::Libplot ':ALL';

$handle=pl_newpl($ARGV[0],\*STDIN,\*STDOUT,\*STDERR);
pl_selectpl($handle);
pl_openpl();

pl_closepl();
pl_selectpl(0);
pl_deletepl($handle);

___END___

Results: X       - an empty window is created
         png,gif - segfault at pl_closepl
         ps      - segfault at pl_deletepl

The bug was introduced when I upgraded from Woody to Sarge.
I suppose this means that the bug appeared in the change from
libplot (2.4.1-7) to libplot2 (2.4.1-11).
