Description Axel Krebs 2012-09-23 16:50:02 UTC 
Application: digikam (2.8.0)
KDE Platform Version: 4.9.1 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
- just want to browse some pics.
- my thumbnails-digikam.db has 8.5 GB
- my digikam4.db has 414,6 MB
- my RAM has 8 GB size
 - I use sqlite

- Is it libtiff again? 
- Could there be other reasons?
- How can I help?

- Is there a reasonable strategy to keep databases smaller?

Axel

The crash can be reproduced every time.

Comment 3 Axel Krebs 2012-09-23 19:55:34 UTC 
Created attachment 74117 [details]
sudden requirement of additional cache-volume?

When I run my PC, I have "system-monitor" running, most of the time. 

Under normal conditions, digiKam need about 3,8 GB memory.
Even, as longs a my thumbnail-database holds about 8,4 GB space. 

When digiKam crashes, the requirement of memory increases. 
Maybe it is useful for you to have this additional observation available!?

No it crash always about litiff issue. There is certainly a huge memory leak when problem occurs...

Unfortunately, digiKam crashes when starting up- on two machines KUBUNTU
11.04, both ~ 8,4 GB thumbnail databases...

I am sorry, I cannot use digiKam anymore these days?

What to do, how to behavieve?

Hope for help.

Comment 6 caulier.gilles 2012-09-26 20:48:55 UTC 
It always crash in libtiff. So i suspect that a tiff file is a problem.

Please try to isolate file and use bug #301045 to report a link on the web where file can be downloaded to test here...

Thanks, I'll try to... tomorrow evening...
Most of the time, crash occurs, with not even having touched a
tiff-file... so: how to sepreate the responsible file?

 :-(

Comment 8 caulier.gilles 2012-09-27 06:17:37 UTC 
The only way to investiguate is to create anew user in your system and create an empty digikam collection. Thake a care to set same digiKam settings than your lead digiKam collection.

After that, import Tiff files until digiKam crash...
