Thanks

Konstantin,

I have implemented some hack in digiKam camera interface to try to clean up this entry. Can you reproduce the crash using current code from svn (0.11.0) ?

Gilles Caulier

Gilles, I will check it later today.

Gilles,

Sorry for the delay.
Now it allowed me to import all the files once from the source directory on SD card, but the second attempt has failed.
The stack trace and the latest console messages are attached.

A stack trace

A stack trace generated by KDE crash analyzer

Created attachment 33596 [details]
A log of messages appeared on the console just before the crash.

I've just figured out that it crashes now only when I'm dragging the dialog window with thumbnails inside across the screen while it is loading. It works correctly if I just wait patiently and do not touch that window until it is completely loaded.
Again, no such behavior on folders with Latin-only names.

digikam(6315)/digikam (core) Digikam::UMSCamera::loadKDEThumbCreator: Mimetype :  "image/jpeg"
digikam(6315)/digikam (core) Digikam::UMSCamera::loadKDEThumbCreator: plugin :  "jpegthumbnail"
KCrash: Application 'digikam' crashing...

These lines give me a hint that the crash comes from loadKDEThumbCreator in UMSCamera. This code has been removed already. Please try again with beta1 or current SVN version.

Yes, definitively. Code removed and fixed with 1.0.0-beta1.

In fact, you have a video file in your media...

Gilles Caulier

Tested that with the latest SVN revision.
Now it works with no crashes, but when I try importing photos
from the same (cursed and damned) folder, the thumbnails are not
shown.
Although everything is imported correctly.

> In fact, you have a video file in your media...

Actually I've tested it both on the whole My Documents folder on an SD card
(containing videos somewhere inside) and on its My Pictures (in Russian)
subfolder containing JPEGs only. Both tests gave the same result.

BTW, if I point it to the My Documents folder (named in English), it displays
thumbnails for all the images from an English-named subfolder, but it shows
default image icons instead for images in the Russian-named directory.

Should I post stderr logs for 'correct' and 'incorrect' import here?
Those logs seem to be useless because the differences between the
outputs are in the times elapsed only.

This is only about the Camera dialog?
Do normal folders in your collection with cyrillic filenames work?
