gscan2pdf doesn't save files

[Christopher]

Binary package hint: gscan2pdf

When saving a scan, the Save window opens as usual and when saving, the most recently used folder opens as usual, but when 'Save' is clicked, the application returns to the Save window in an endless loop.

This is a Maverick issue, not affecting Lucid.

Apologies for crossposting the gscan2pdf-help list, Debian, and Ubuntu
bugs, but it makes no sense to have the same conversation three times.

I've installed the main dependencies from sid and still can't reproduce this.

Does it make a difference if the image is imported or scanned?

Please apply the attached patch, which simply adds a couple of
debugging messages so that I can home in on where this coming from,
start gscan2pdf with the --debug option, try to save a PDF, quit, and
post the output from the command line.

Regards

Jeff

Before I add the patch, I wanted to advise that I can save in all the image formats, but not the hybrids PDF or DejaVu. I remember this exact problem with previous Alphas, notably Karmic.

I haven't found that it makes a difference if it's imported or scanned. It makes me wonder if it's a Xorg bug, as so many oddities can be traced back to it on Intel 9xx displays.

Please let me know exactly how to apply patches, as i haven't yet acquired that skill. Keep in mind that I'm a musician first and foremost and therefore very GUI oriented, but I can learn code when at gunpoint.

Importing does not work either, here is the output:

typescript attached. No output about saving, and on quit, I was
asked whether I wanted to leave the program without saving.

Although assuming this was a two-liner from pdfTex, it probably didn't
have an image in it, and therefore would have imported nothing anyway.
Can you import an image (PNM, PNG, etc.) or a PDF with an image in it?

Did you apply the patch before producing the debug output?

[Christopher (soft-kristal)]

For what it's worth, I can scan and save PDFs using Xsane, but I get multiple popup errors, all with this message:

Error during CMS conversion: Could not open scanner OCM profile:

sudo patch /usr/bin/gscan2pdf < debug.patch

[Christopher (soft-kristal)]

Pasting the debug output file is too large to paste here, so I'm attaching it as a text file.

Yes. And I tried with a PDF with an image (imported a previously
scanned page), but there was no output relating to saving, and
saving didn't work.

The logging system was previously just print and warn calls. I've now
replaced all that using Log::Log4perl and added a couple of command
line options to support it. I've uploaded a .deb to
http://launchpadlibrarian.net/52500599/gscan2pdf_0.9.32~1_all.deb

There are no other significant changes, apart from a couple of extra
debugging messages. Please install. You might need a

$ sudo apt-get install liblog-log4perl-perl

first.

If you start the program with

$ gscan2pdf --log=<log file>

It will default to 'debug' level messages, which will be printed to
the terminal window and to <log file>.

Please do so, reproduce the bug, quit, and post <log file>.

I installed the package, but nothing has changed - I still can't save the scan, and it still overrides the document name with today's date.

The basic behaviour didn't change, but the behaviour of the logging
should have. Please start the program with

$ gscan2pdf --log=<log file>

reproduce the problem, quit, and post <log file>.

Thanks for this. It seems the problem is related to GTK2 or the Perl
bindings - the file browser should return 'ok' or 'cancel' on
selecting the filename, but:

DEBUG - PDF save filename dialog returned -5

I'll install the relevant packages from sid and see why...

It is the Perl bindings for GTK that are the problem. I'll work up a
patch, or if necessary a test case and submit the appropriate bugs.

In the mean time, if you downgrade libgtk2-perl and libglib-perl, then
you should be able to save again.

[Christopher (soft-kristal)]

Hey - that's why I have the stable Lucid on my main partition. It doesn't take long to reboot and do what I have to do with it's working version.

The reason I have partition for Alphas is to be a willing participant in new ideas, warts and all. As long as it boots, I'll keep it.

[Jeffrey Ratcliffe (jeffreyratcliffe)]

Please sync libglib-perl 1.223 and libgtk2-perl 1.222 from sid, which fix this bug

[Stefano Rivera (stefanor)]

Jeremy: What action do you want sponsors to take? (unsubscribing sponsors for now).
You can request syncs with requestsync: https://wiki.ubuntu.com/UbuntuDevelopment/Merging

[Christopher (soft-kristal)]

What fix? It's still not saving PDF, PS or DejaVu.

[Stefano Rivera (stefanor)]

Syncs requests filed:
* libglib-perl: bug #615279
* libgtk2-perl: bug #615280

[Stefano Rivera (stefanor)]

Both have been synced and should appear in the archive soon. Can a maverick tester please upgrade to them and see if this bug is still present?

[Christopher (soft-kristal)]

This morning's update to libgtk2-perl fixed the problem. Still won't save inputted filename, but I can deal with that.
