gnome-web-photo crashed with SIGSEGV in strlen()

[Jorge Hernández]

Binary package hint: gnome-web-photo

When called from a php script running in Apache (though I've had the same results using Ruby and/or lighttpd):

<?php
        exec("xvfb-run -e error.log -s \"-screen 0 1024x768x24\" -w 0 gnome-web-photo www.google.com google.jpeg");
?>

Ubuntu: 8.04.1
gnome-web-photo: 0.3-0ubuntu2
Apache: 2.2.8-1ubuntu0.3
PHP: 5.2.4-2ubuntu5.3

The following does not SIGSEGV:

root@jd:/var/www# sudo -u \#33 php5 photo.php

I managed to get it to run. The SIGSEGV stems from the fact that Apache runs processes with an empty $HOME and at no point in time does xulrunner check that $HOME is non-empty.

I have also encountered this problem, when trying to run gnome-web-photo, using xvfb, python, and apache2 (Ubuntu 8.04). Are there any know fixes or workarounds for this bug?

[loke (developer-loke)]

The problem happens because of its integration with Gnome. You would need to provide environment variable for home to /var/www. and create .Gnome2 and .Gnome2_private folders there which should be writable by apache. After that the problem should disappear.
