Bug 350632

Hi Mr. Chandran,

I now tried to reproduce it with gwenview git master ( commit 53887db3ad6c63c784e410ea6c61d8d8943d7031 ) with a patch for the UI - with this image which is one of the largest I could find in a Google search for "fantasy art": (safe for work/child safe): http://sf.co.ua/13/08/wallpaper-2958231.jpg , and rotations is working fine. I'm using Mageia Linux x86-64 v6.

1. Can you still reproduce this problem with git master of gwenview?

2. Can you provide an offending image?

backtrace of a similar crash

Just as I wanted to rotate a picture gwenview crashed so that I can confirm this bug.

Please provide a problematic picture and details of your gwenview version and system.

I am using Kubuntu 15.04 and it should be the version of gwenview from the Kubuntu backports PPA.

I see. Please provide a problematic image file.

picture for testing the bug

If you try to rotate the picture repeatedly, i. e. pressing Ctrl-R quite often, then there should certainly occur a crash.

Maybe this reveals something, too. When I started gwenview from the terminal, these messages where displayed on it:

I cannot reproduce it here (= Mageia Linux x86-64 version 6) with either gwenview-15.08.1-1.mga6 or with gwenview from git master ( 

commit 53887db3ad6c63c784e410ea6c61d8d8943d7031

). I tried pressing Ctrl+R many times with that photo in gwenview, and even held ctrl+R and no crash was seen. Can you try it with the git master version?

On Debian testing with Gwenview 15.08.1 (Frameworks 5.14.0, compiled against Qt 5.4.2) this issue does not occur, too.

I see - thanks for the update.

I see the crash consistently with at least one photo when I click the rotate button twice very quickly.

can you share a problematic photo? You can try attaching it here or use http://imgur.com/ .

test photo

Hi Yasin,

I tried rotating your photo rapidly in gwenview on both an Ubuntu 16.04+backports VirtualBox VM running JWM And on my Mageia Linux x86-64 v6 system running Xfce, and there were absolutely no crashes. Can you try to see if it is happening in a new UNIX user account on JWM or a similar lightweight window manager?
