Sentry Crash Report:

Description Christian González 2011-04-06 21:10:58 UTC 
Application: digikam (1.8.0)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

Deleting a folder within digicam is VERY laggy here, it often needs  more than 5-10 seconds (!) to have an empty folder deleted, meaning: 
* right-click on an empty folder, select "delete", confirm
* wait a few seconds
* the folder vanishes from the view on the left side

you have plenty of time to click again on the (recently deleted) folder again - digicam crashes.

Maybe the main bug is the laggyness - it feels like working on a 286 -I am using a Quad-core Phenom CPU and a Nvidia GT 240, this should do for tree drawing ;-)

I don't know exactly what digiKam does in the background when selecting a folder, but IMHO there are much too many things triggered by a click, it seems to have much work (selecting an empty folder!)

The crash can be reproduced every time.

-- Backtrace:

Comment 1 Christian González 2011-04-06 21:23:18 UTC 
Additional info, what I did before:
I have a folder structure like
Foo
 +-Bar
 +-Blu

In "Bar" are some MBs (100?) of photos, I open the folder the first time, so digiKam has to build thumbnails, what is CPU-consuming. While that I drag&drop (move) them up into "Foo" - after the movement is complete "Bar" is empty, but the thumbnails are not finished, so digiKam is still busy.
Now I delete "Bar" - it is laggy now, so I have time to click another time at "Bar" - crash.
Comment 2 caulier.gilles 2011-04-06 21:38:44 UTC 
Can you try with digiKam 1.9.0 ?

Gilles Caulier
Comment 3 Marcel Wiesweg 2011-04-07 22:19:02 UTC 
Can you reproduce the crash with 2.beta?
Comment 4 caulier.gilles 2011-07-06 11:18:50 UTC 
We need feedback using a recent version. 2.0.0 RC is out, please test...

Thanks in advance

Gilles Caulier
Comment 5 Christian González 2011-07-07 19:49:24 UTC 
I tried it with 1.9, same issue, I can' tell you with 2.0 as I don't know any Ubuntu ppa where I can install version 2.0 there, so I can't test it.
Comment 6 Richard Mortimer 2011-07-07 19:59:04 UTC 
Philip Johnsson produces regular PPAs for digikam. You can find 2.0.0 RC as per his recent posting to the digikam-users list.


You find the PPA at: https://launchpad.net/~philip5

If you don't know how to use the PPA with Ubuntu 11.04 (Natty) then
visit this link:

http://www.mohamedmalik.com/?p=1019

I believe that there is also a 10.10 Maverick version of the PPA but I haven't looked since I recently upgraded to Natty.
Comment 7 Christian González 2011-07-08 18:25:04 UTC 
ok, I had this ppa before but didn't find an update for digikam - now I saw that he named it "digikam2" (the package) - but the executable is "digikam" - is it a transition package?

The crash seems to be gone, so AFAICT the bug is closed.
The laggyness is still there. Just normal navigation in the tree is so slow that I have to move away from digikam, sorry.
