Description
This is related to [[http://linhes.org/flyspray/index.php?do=details&task_id=282|report 282]] and the perl dependencies of the Shepherd tv_grab_au script.
The two most important grabbers use the perl JavaScript module and both produce a segmentation fault when using the perl-javascript package. I uninstalled perl-javascript (keeping the spidermonkey dependency) and reinstalled the JavaScript module using cpan. Now the scripts work, or at least are no longer seg. faulting.

Can you please provide more information. Others have report no issue w/ the package. Perhaps an output of the segfault.

This is the type of thing I was seeing in /var/log/messages.log
Jun 9 09:45:08 mythbox news7327: segfault at 465475 ip b7fbe4f0 sp bfc72990 error 4 in libpthread-2.9.so[b7fb7000+14000]

And the code which dies is the following (actually the $jsc->eval line)
sub setup_javascript
{
print "Initializing JavaScript interpreter.\n" if ($debug);
$jsc = new JavaScript::Runtime->create_context();
$jsc->set_error_handler( sub { } ) if (exists(&JavaScript::Context::set_error_handler));
$jsc->eval(qq{
var doc = '';
function Location() { this.href = '$DATASOURCE'; }
function Document() { this.write = function(x) { doc += x; } }
function Window() { this.___ww = 0 }
location = new Location;
document = new Document;
window = new Window;
});
}
When I installed the JavaScript module I was asked if spidermonkey was threadsafe, to which I answered yes (after checking the compile flags in http://knoppmyth.net/repo/src_packages/extra-testing/spidermonkey-1.7.0-2.src.tar.gz). All of the tests passed fine.

I am having a similar problem to others with shepherd segfaulting.
R6.0.0.8 Fresh Install. Then I installed shepherd using:
sudo -Sy shepherd-dep
cd~
wget http://www.whuffy.com/shepherd/shepherd
perl shepherd
The install worked great. Even grabbed nice channel icons for me. very cool.
I then ran mythfilldatabase and it segfaulted.. so i did the following:
[root@mythtv ~]# pacman -Sy shepherd-dep

Any help would be greatly appreciated. I am so close to having a fully functioning myth system again!! Please let me know if there is any further info i can provide

Same segfault problem here on a fresh R6.00.08
Shepherd installed "sudo pacman -S shepherd" no problems.
Both rex and news grabbers show "failed code 139" in "~/.shepherd/shepherd --status" and shepherd.log
06:03:11 HTPC news14848: segfault at 2d ip b7ee74f0 sp bfa9bfc0 error 4 in libpthread-2.9.so[b7ee0000+14000]

Unless users run shepherd(mythfilldatabase) manually, or check their shepherd.log file they probably will not be aware of this problem as other grabbers within shepherd will usually be able to provide tv data. Running something like "mythfilldatabase --graboptions '--notquiet --notimetest'" would let you watch shepherd run and perhaps be helpful?

I installed JavaScript using cpan and answered 'yes' for threadsafe spidermonkey, then 'no' for the other questions. The compile proceeded a lot better than when i had answered 'no' for threadsafe.
Do this has stopped the seg faults, and shepherd now uses the news and rex grabbers successfully. Attempts where I'd answered no for threadsafe didn't not fix my issues.
