Subject: should not warn about missing DISPLAY when used at the command line

Date: Fri, 25 Jul 2008 20:53:46 +0200

Package: dia
Version: 0.96.1-7
Severity: minor

Since PyGTK is "integrated" into dia, it warns about about
missing DISPLAY, when running at the command line (and DISPLAY
is not set):

$ DISPLAY='' dia --export=foo.png foo.dia
/var/lib/python-support/python2.5/gtk-2.0/gtk/__init__.py:72: GtkWarning: could not open display
  warnings.warn(str(e), _gtk.Warning)
foo.dia --> foo.png

Running dia with no DISPLAY is no reason to complain.
(Btw. the "foo.dia --> foo.png" line is waste, as well.)

The error occurs when running in a sid pbuilder chroot the used dia version is 0.97-2 too.

The ldap-is-a-tree.dia file comes from the ldaptor source package (I attached it to #538309).

Hi,

for the record, I can't reproduce the segfault in a pbuilder chroot.
What remains is the (valid) issues of:

- "... --> ..."
- DISPLAY warning
