Andi, none editor tool use libjpeg. All are based on DImg transformation code.

I somehow just read "rotation tool"....
But rotation in CameraUI is working, too.

So to sum it up:

- DImg jpeg loader => WORKING
- rotation tool from cameragui (libs/jpegutils) => WORKING
- jpeglossless plugin => BROKEN (will crash application on startup)

SVN commit 998312 by aclemens:

When messing with pointers, always check if they are valid.
This gives another backtrace now, which seems to confirm my guess that
the libjpeg update is responsible for the crash.

Ok digiKam starts now, but when I use the plugin, it crashes with the following
backtrace:

Why jpeg_destroy crash plugin here:

http://lxr.kde.org/source/extragear/graphics/kipi-plugins/jpeglossless/jpegtransform.cpp#177

It's exactly the same code in digiKam core :

http://lxr.kde.org/source/extragear/graphics/digikam/libs/jpegutils/jpegutils.cpp#444

What's the difference...

Gilles

Good question, I'm comparing the two functions at the moment, but they look
really the same.
This is weird.

After removing and installing libjpeg again, it seems to work for me.
Strange. Since no one else confirmed this issue, I will close the report again
and mark it as invalid as it was before.
