[Pkg-dia-team] Bug#538309: more information how to reproduce the issue

Fri Jul 24 19:05:22 UTC 2009

the issue occurs when $DISPLAY is not set (i.e. when run from pdebuild
in cowbuilder)

here is how to reproduce the problem including a gdb session with
libgtk2.0-0-dbg installed:

ldaptor-0.0.43/doc> unset DISPLAY ; gdb -w --args dia -t png-libart --export=ldap-is-a-tree.png ldap-is-a-tree.dia
