            Bug ID: 102106
           Summary: xorg crashes when running gscan2pdf (libgtk2-perl)
                    test case
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: jffry at posteo.net
        QA Contact: xorg-team at lists.x.org

* What led up to the situation?

Download and extract the source:

wget
http://http.debian.net/debian/pool/main/g/gscan2pdf/gscan2pdf_1.6.0.orig.tar.xz
tar xvfJ gscan2pdf_1.6.0.orig.tar.xz
cd gscan2pdf-1.6.0

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Run one of the test cases:

PERL5LIB="blib:lib:$PERL5LIB" perl t/114_cancel_save_pdf.t

   * What was the outcome of this action?

xorg crashed, and I was returned to the login screen

   * What outcome did you expect instead?

The test should have run through as normal

I tried to debug the problem by installing xserver-xorg-video-nouveau-dbg, ssh-
ing to the computer from another, starting gdb and attaching the PID of the
xorg process.

As long as gdb is attached to the process, and the -dbg package is installed,
xorg does not crash. Otherwise, it crashes every time. Not all the test cases
are affected. The 67 tests that run before this one, run fine.

If it does crash, it takes the ssh process with it, so I can't see the gdb
output.
