Description Colin Baker 2011-04-20 01:37:24 UTC

Application: digikam (1.4.0)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Opening a folder & waiting for thumbnails to generate.  Also occurs while opening the file.

- Custom settings of the application:
Crash only seems to occur with grayscale DNG RAW files created by Vuescan scanner software.  Color files are ok.  I can provide sample files if necessary.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault

Comment 1 caulier.gilles 2011-04-20 08:50:06 UTC

It's probably a bug in libkdcraw. 

Go to help/Components Info and copy and paste all content.

I recommend to update digiKam to last stable 1.9.0 and also libkdcraw if possible.

Can you provide a link to your DNG image to test in local ?

New crash information added by DrKonqi

1) Start digikam

3) Building thumbnails...... and crash

Comment 3 caulier.gilles 2011-05-26 08:17:14 UTC

Dmitry,

Can you send me the image responsible of this crash ?

Note : i suspect a libkdcraw binary compatibility issue on your computer. If it work on mine, it will confirm it.

Also, i need to know the libkdcraw and libraw version that you use.

Comment 4 Dmitry 2011-05-26 23:17:32 UTC

Hi!

Operating System: Linux 2.6.38-8-generic #42-Ubuntu SMP i686
Distribution: Kubuntu 11.04


I have long sought to understand the patterns of failure digikam.
Found a few files. If their mark in the album, digikam crash. I suggest to download one of them - http://www.rirc.ru/images/scan0003.dng (Size 21M) If a lot of files in the album, the crash quickly. To reiterate my problem, I always do this:

Open/Close album,
Several times clicked on the album,
Click on the icon to rotate the image.
Digikam is usually crash.

I could not find installed libraw. Probably it is part of another package? I found that I had a version of the libkdcraw9:

Dmitry,

Libraw library is include in libkdcraw.

Go to Help/Components Info from digiKam menu and copy and paste the contents here.

Also, i suspect that 2 version of libkdcraw is installled on your system. Please check...

Grayscale DNG open by Showfoto

Comment 7 caulier.gilles 2011-05-27 06:14:54 UTC

Alex, 

Look like with Dmitry DNG image, Showfoto open strongly this RAW file. I attached a screen-shot to this file.

I use last libraw of course, as you can see in components info dialog.

Note that Showfoto don't crash here.

Comment 8 Alex Tutubalin 2011-05-27 07:08:55 UTC

Hello!

The dcraw_emu sample (from latest LibRaw 0.13.5) extracts nice cat BW negative from the sample file. I've tested under Windows7, will try unix version later today.

The resulting image is black and white (one component, not three), may it cause the problem on the later stages?

Comment 9 caulier.gilles 2011-05-27 08:37:05 UTC

Alex,

You want mean that color depth of image data extracted from libraw, can be different than RGB ? Same about JPEG embeded preview image ?

Comment 10 Alex Tutubalin 2011-05-27 09:08:08 UTC

For dcraw_make_mem_image call you *should* take libraw_processed_image_t.colors field into account. For grayscale image this field is equal to 1 and bitmap allocated according to exact color count:
 === quote from source ===
unsigned ds = S.height * S.width * (O.output_bps/8) * P1.colors;
libraw_processed_image_t *ret = (libraw_processed_image_t*)::malloc(sizeof(libraw_processed_image_t)+ds);
...
ret->colors = P1.colors;

For thumbnail things are simpler:
 for libraw_processed_image_t.type == LIBRAW_THUMBNAIL_BITMAP  the libraw_processed_image_t.colors is always 3
 and for libraw_processed_image_t.type == LIBRAW_THUMBNAIL_JPEG the thumbnail is JPEG data (libraw does not analyse this type of thumbnails)

Comment 11 caulier.gilles 2011-05-27 09:20:26 UTC

Alex, 

i think i found the problem : it's in PPM creation header :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkdcraw/repository/revisions/master/entry/libkdcraw/kdcraw_p.cpp#L61

For grayscaled image, i need to set header with P3 (PGM), not P6 (PPM)

Gilles Caulier

Comment 12 caulier.gilles 2011-05-27 09:46:33 UTC

Alex,

Sorry, i would said P5 for PGM, not P3...

Gilles

Comment 13 Alex Tutubalin 2011-05-27 09:50:47 UTC

dcraw uses:
 if(colors>3) "P7"
 else "P%d",colors/2+5

:)
