gscan2pdf does not start on Ubuntu 9.04

[Dakkar]

Binary package hint: gscan2pdf

After upgrading to Ubuntu 9.04 development branch, gscan2pdf does not start at all. Scanner is working in other applications (ex Xsane scanner utility)

If I try to start gscan2pdf from the command line by typing "gscan2pdf" I get this message :

"/tmp/tnexKMvNv6/session" does not exist within ConfigPath: /tmp/tnexKMvNv6! at /usr/bin/gscan2pdf line 1581"

Thanks!

It looks like gscan2pdf is relying on a session file in the /tmp directory, which is being purged for some reason (cron, or startup; I am not sure of how ubuntu handles /tmp).
The link to that nonexistant session file (inside 'ConfigPath') is part of gscan2pdf's per-user settings file, in the logged-on user's home directory: ~/.gscan2pdf

So, simply deleting this file will allow the app to start, albeit with the default configuration (minus anything that was saved in that settings file).

In my office I've just placed a perl script on the desktop of all scan PCs:
#!/usr/bin/perl

exec("rm ~/.gscan2pdf");

This is obviously a temporary solution, and not even a very good one ;)

So, good luck.

This is known problem, fixed in the upcoming release.

The problem only occurs when gscan2pdf is not shutdown cleanly, and then the temp area is deleted before gscan2pdf is restarted.

If gscan2pdf is restarted first, then it will restore the previous session.

How about

#!/bin/bash
rm ~/.gscan2pdf

or even

#!/bin/bash
mv ~/.gscan2pdf ~/.gscan2pdf.old
grep -v session ~/.gscan2pdf.old > ~/.gscan2pdf
rm ~/.gscan2pdf.old

Hi,

Thanks for the reply. Yes, I followed your instruction and it work.
I just tried again on reboot and it still works.

Thanks for solving the problem!
