Crash at startup

Binary package hint: gscan2pdf

When I start gscan2pdf from command line I get the following:

Works fine here. Do you get this every time?

Marked as invalid, I can't reproduce on an updated karmic.

I have the same issue:

I have the latest current stable version (10.04) with updates.

I attempted a basic un-install and re-install and it appears to have had no effect and the list of packages install is the same before un-install and after re-installing.
I will attach the list of packages installed when gscan2pdf is installed and also when it is un-installed.

[1guess (ubuntu1-1guess)]

After modifying forks.pm to output the $PORT in the croak at line 2126 and 2131, I could confirm it was not a reserved port. I then realized that my firewall was blocking the connection (127.0.0.1). I disabled the firewall (iptables) and the application ran perfectly without issue. My issue has been resolved.

The steps I used to disable my firewall are:
#iptables --flush
#iptables -X
#iptables --policy INPUT ACCEPT
#iptables --policy FORWARD DROP
#iptables --policy OUTPUT ACCEPT

I manually modified my firewall settings and re-enable to permanently resolve this issue.

Firewall configuration as suggested by 1guess on 2010-10-05 did not help me.

gscan2pdf does not depend directly on IO::Socket::INET, so this is not
a bug in gscan2pdf.

However, assuming that this is a problem with forks, try swapping
forks for threads, as per this patch[1]
