#300 gscan2pdf produces

Similar to:

I get
Error running unpaper: [image2 @ %x] Encoder did not produce proper pts, making some up.

For every page of every doument every time.

Worse, they come up in random order, but I have to close them in reverse order they opened! The close box works on only one at a time! Ubuntu 16.04 LTS version 1.3.9

You don't say which version of gscan2pdf you are using, but recent
versions included a tick box in the warning window "Don't show this
message again", which should suppress similar messages in subsequent
runs of the tool.

Please start gscan2pdf from the command line with the --log=log option,
reproduce the problem, quit and post the log file.

Per above: Ubuntu 16.04 LTS platform, Gscan2pdf Version 1.3.9

The full log has the names of personal documents (trusts and wills). Here's the last section:

When I saw the error message, I was unclear if it was ignorable, or serious.

[Jeffrey Ratcliffe]

The errors are from unpaper - gscan2pdf is just passing them on. They don't seem to be serious.

That version of gscan2pdf is over 2 years old. I suggest you upgrade to the latest via the PPA.

[Bryce Nesbitt]

On Ubuntu, upgrades outside of the platform often don't go well.
Unfortunately.

If this error is ignorable, perhaps ignore it by default?

That is rather my point. The latest version does a much better job at ignoring warnings/errors like that.

The PPA isn't really outside the Ubuntu platform. If you look at the gscan2pdf on Ubuntu, I am listed as maintainer, not because I am an Ubuntu developer, but because Ubuntu takes gscan2pdf directly from Debian, and I am a Debian Developer and create the gscan2pdf Debian packages:

https://launchpad.net/ubuntu/+source/gscan2pdf

https://launchpad.net/~jeffreyratcliffe/+archive/ubuntu/ppa

The packages in the PPA are built by Ubuntu against the appropriate Ubuntu release, using the source I provide.

[Jeffrey Ratcliffe]

The latest release also collect the error messages into one window, meaning there is only one window to close.
