Affects Status Importance Assigned to Milestone
Simple Scan
Fix Released

Bug Description

Installed by: "sudo add-apt-repository ppa:robert-ancell/simple-scan"
Current version (as reported by the Help -> About) is 0.9.9.
Running on Kubuntu 9.10, with KDE 4.4.1

I'm scanning multiple pages from the ADF (this is an HP Photosmart C7280)
The scan works BEAUTIFULY!!!
Click to save the pdf, and simple-scan just disappears.

Could you run with simple-scan -d and paste the output here?

Also, does this always occur? Does it occur when saving only one page?

Jay Gindin (jayg) wrote :

Attaching output from "simple-scan -d".

I also verified that a single page scan does seem to work. (However, I notice that the page is scanned 90 degrees sideways, works, and you're kind enough to provide the rotation buttons :-)

Hi Jay,

Is this still a problem? The crash shows that is is ImageMagick that is crashing, I haven't had any duplicates so I'm thinking there is a problem in your installation.

You can test ImageMagick by making some TIFF and JPEG files (save from simple-scan with .tiff extension or use GIMP etc) and run the following command (which is what Simple Scan is doing):
$ convert -adjoin file1.tiff file2.jpeg output.pdf

Could you please experiment with the images you are scanning and see if you can work out what reproduces the problem?

(also, please look in /tmp after the crash to see the temporary files that Simple Scan created. If you can reproduce please attach the files that cause the problem)

Jay Gindin (jayg) wrote :

I created 2 simple files in GIMP, pg1.tiff and pg2.jpeg. Running the "convert -adjoin pg1.tiff pg2.jpeg output.pdf" causes a segmentation fault.

I've got imagemagik 7: installed.

I guess this probably isn't an issue with simple-scan, but none-the-less, I'd appreciate any pointers you may have on where to start my investigation with imagemagik...I have about zero experience with that package...

Thanks for your helpfulness in figuring out this issue...

I think I have the same problem with multiple pages but only (ithink) when converting form .jpg to .pdf, Scanning and saving works perfectly with single pages.

Here is the (edited as marked "...") output of "simple-scan -d" first saving multiple pages as .jpg which worked and then saving multiple pages to .pdf which didn't. I hope this is of some help.

Hi there,
same problem here. Simple-scan works and I saved already a couple of jpegs (siglepage)

Today I wanted to scan 2 pages and save them as pdf
attached is the output from simple-scan --debug >simple-scan.log

same problem for me. If I save one page, no problem but if I save 2 pages or more, it crashes.

Sorry for my english

Esteban (jesteban20) wrote :

Maybe it would be helpful, I found that if you keep it in *.ps it don't crash.

Robert Ancell (robert-ancell) wrote :

Fixed the crash if ImageMagick fails. (Note this does not the save from failing if you have a broken version of ImageMagick).

What version of ImageMagick seems to be working? Is it a newer version that what I posted I'm running (7: Is it perhaps a missing dependency? Or, if you're not sure, could you post the version(s) you have tested with?



sebastian-s (sebastian-s) wrote :

Hi Robert,
thanks for the quick fix

Was is a simple-scan bug at all? and what version of simple-scan will contain the fix?
Does it require a particular Imagemagick version?

Robert Ancell (robert-ancell) wrote :

It appears the Karmic version of ImageMagick has a bug - it works fine in 10.04 (7: If you are experiencing it please file a bug against the Karmic package (if one does not already exist).

The bug was simple-scan not correctly handling ImageMagick failing:

Robert Ancell (robert-ancell) wrote :

sebastian-s, no particular version is required, just that the following command works:
$ convert -adjoin file1.tiff file2.jpeg output.pdf

(note that the use of ImageMagick is a workaround until cairo supports compressed images in PDF files, this should also speed up the saving process).

Same here.
Saving 2 pages as PDF crashes.
Saving 2 pages as jpeg works.

Had the same problem at Ubuntu 9.10 using Simple Scan 1.0.3, upgrading imagemagick using this PPA solved my problem:

Since yesterday I have similar problems with simple-scan. Before it allways worked fine! But yesterday, after scanning some pages it crashed while saving to PDF. The first time I get this message from shell:

simple-scan shut down and the file was corrupt.

And next, I scaned one a few pages and saved it without error. But afterwards I get another message while simple-scan brokes:

I think the error this time occured at the end of saving-process, because the PDF was created correct.

The current used version of simple-scan is 2.32.0 with Ubuntu 10.10

I still experience this bug with Simple Scan 3.4.3 for Linux Mint 13 (Maya) 64 bit with Gnome 3.4.2.

It appears there isn't a fixed version avalaible in standard application repositories.
