Sentry Crash Report:

Description Mauricio 2014-03-22 04:34:37 UTC 
Application: gwenview (4.12.2)
KDE Platform Version: 4.12.3
Qt Version: 4.8.6
Operating System: Linux 3.11.0-18-generic x86_64
Distribution: Ubuntu 13.10

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

So, I discovered this bug by mistake. Gwenview apparently does not automatically update the image when I ue "Plugins > Images > Convert to Black & White" (however, it does convert the image). So I clicked on it a second time and Gwenview crahed. I tried this again, and every time it happens.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault

Comment 2 caulier.gilles 2014-12-10 17:57:40 UTC 
Kipi-plugins 4.5.0 have been released.

Crash still reproducible with this release ?

Comment 3 Mauricio 2014-12-10 22:03:53 UTC 
This is what happens

1. Open image in Gwenview
2. Plugins > Images > Convert to Black and White
3. Image is converted, but Gwenview still shows in color
4. Plugins > Images > Convert to Black and White
5. Gwenview suddenly closes

gwenview --version

KDE Development Platform: 4.14.2
Gwenview: 4.14.0 pre

How do I get the plugin versions?

By the way, I've tried other plugins (e.g. flip, rotate). Gwenview does not update the image for any of them, but it only closes up when I use the black and white plugin twice.

New Kipiplugins 4.11.0 is available :

Can you reproduce the problem with this release ?

The link instructed me to install kubuntu backports. I did and it messed up my system.  Is there a link to a .deb? I might try building from source later in the week but I wont try backports again.

JPEGLossLess tool is not maintained and now obsolete with 5.0.0

I'm really sorry about the delay. I've just realized that the reason I can't use plug-ins in Gwenview is because i am on KF5... I guess if it's obsolete now this bug report is no longer valid?
