Description Tim 2008-03-15 22:56:49 UTC
Version:           0.9.2 (using KDE 3.5.8)
Installed from:    Debian stable Packages
OS:                Linux

I am running mepis 7 (a Debian stable drivative), Digikam comes from the debian etch repos. Due to bad house keeping in the past of my digital pictures I have had to re-do the exif data on several thousand pictures.

Here is the problem, open a console and start top, now open digikam, select an album of picture (around 20+ pictures should do, for the record mine are in .jpg format and around 2mb in size), select all the pictures in the album, now goto Image menu >> metadata >> edit exif data from the window that opens change the year on the "Original date" and Digitisation date" then click forward, do this to about 6 pictures then quickly click back to the console and note what taking all the processor.

On my box I find that two program starting hogging the processor sending it to 99% useage and the temperture climbing slowly until I have to stop for a break. The two programs in question are:

Kio-digikamdate (the worst offender)
Kio-digikamalbu

My box is a P4 2.8ghz with 1gb of memory which has 600mb+ of free memory while carrying out the above.

This problem is relevant of digiKam KIO slaves which are dropped since version 5.0.0 in favor of a multithreaded interface to query the database. It will not reproducible.
