-- Information about the crash:
- What I was doing when the application crashed: I was assigning tags to a large collection of photos. I initiated the rotation of two photos. It was very slow. I jumped to check system monitor information. virtuoso taking the most of CPU, 9% at that moment. Digikam taking most of my 4gb memory. All of sudden digikam crash message popped up.

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

This looks like a issue deep inside libjpeg which is used by digikam. Please report the problem to the libjpeg developers.
Comment 2 Johannes Wienke 2010-08-15 11:53:59 UTC
Thinking about this once again it may also have been cause by a memory leak that existed in 1.3.

Marcel, what do you think?
Comment 3 Marcel Wiesweg 2010-08-21 15:51:30 UTC
Happens in libjpeg when loading a file for thumbnailing. For a memory leak, out of memory, I would expect a failed new or malloc() call, this really looks like a plain invalid memory access.

Heikki, can you reproduce? Do you know which file was causing this? It is probably a JPEG file, and the filename was probably printed on the console before the crash occurred.
Comment 4 Heikki Välisuo 2010-08-22 10:48:56 UTC
Hi Marcel,

Sorry, I am afraid I cannot give any useful details. Some backgroud: I had copied 
nearly 30000 photos in my new computer. I asked digikam show me the main album 
with all its subalbums in the thumbnail view. Because I did not copy the old 
thumbnails  database, digikam was creating new thumbnails to all the photos.

Quite a long time before the crash I noticed that at least one of the thumbnails 
was incorrect. I could not recognise the thumbnail. Maybe it was a small part of 
the photo or something else. Because the photo was not too interesting, I deleted 
the photo. What I want to tell is that I had been all kind of things with a large 
collection of photos and may have corrupted some of them. 


In the evening I can delete the thumbnails database and make digikam recreate it. 
If it crashes again, then we have something.
