Description Roger Larsson 2012-04-19 17:19:01 UTC

I see the thumbnails begins to view and then it crashes.
100% reproduceable.

Interesting: not only image files are stored in the directory mp3 and other files are mixed in... (In the DCIM directory there are only .jpg and .mp4 but Digikam import lists all directories...)

Full -debuginfo is installed, but somehow it is not enough for the wizard

Application: Digikam (digikam), signal: Segmentation fault

Reproducible: Always

Steps to Reproduce:
1. Connect N900, select Mass Storage mode
2. Start Digikam
3. Choose Import USB

Actual Results:  
Directly when thumbnails starts to show up digikam crashes...

Expected Results:  
All media should be shown and I should be able to import selected media

Work around:

Open import tool toward other memory.
Select "JPG/TIFF-files" or "Video-files"
Close that.

Now open N900 again - no crash (the filetype setting helps).

Comment 1 caulier.gilles 2012-04-19 21:16:28 UTC

Sound like an old problem fixed with 2.5.0 release. Please update and try again.

Also previewjob from KDE, is used here to display video thumbs. I suspect a video codec problem on your computer.

Here i use a N900 too, without any problem...

Comment 2 Roger Larsson 2012-04-19 22:31:55 UTC

Forgot to mention that I usually have had no problem with N900.
But I guess that some file gives me trouble...
Nice to hear that the problem most likely have been fixed in 2.5.0

Comment 3 caulier.gilles 2015-06-26 13:44:13 UTC

New digiKam 4.11.0 is available :

Comment 4 caulier.gilles 2015-08-22 06:41:04 UTC

digiKam 4.12.0 is out :

https://www.digikam.org/node/741

We need a fresh feedback using this release please...
Thanks in advance.

Comment 5 caulier.gilles 2016-07-15 16:15:30 UTC

With digiKam 5.0.0, this problem is not reproducible.
I close this file now. Don't hesitate to re-open if necessary.
