Closing pinta in Fedora 18 does NOT close pinta

[No Name Dot C]

After using pinta, closing pinta does not actually close the software. I generally have to kill the process from a terminal.

The error message that I get is

"Unhandled exception:
Exception has been thrown by the target of an invocation."

Details:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

Just a note that this problem was not there in the previous version.

[Roland (Rolandixor) Taylor (rolandixor)]

Confirmed. Happens on Ubuntu 13.04 64bit for me as well.

[Cameron White (cameronwhite91)]

Are you using Pinta 1.4, or the 1.5 development version?

Also, does this happen every time, or only after certain actions? (this sounds similar to bug #1075472)

[No Name Dot C (nonamedotc)]

I am using Pinta 1.4.

This happens every single time I open an image (image format does not matter). If I open pinta and just close it without opening any image, it closes normally.

I am getting this "System.NullReferenceException: Object reference not set to an instance of an object" too in pinta-1.5-preview-20130309 on Windows XP, but not on every close, but only on some of them - so in my case it looks like there is some special combination that I use that appears in crash - so it may not be the same problem... I am getting this error constantly, but I am just unable to replicate it to have exact step-by-steps instructions - when I do I will update this report or open a new one.

[Cameron White (cameronwhite91)]

It looks like the crash occurs when saving Pinta's settings. Is Pinta able to successfully create the settings directory for you? It should be under ~/.config/Pinta

[No Name Dot C (nonamedotc)]

Yes. There seems to be no problems in doing that.

$ ll ~/.config/Pinta/

Happens to me in Ubuntu 12.04 PP LTS with similar message or the same.
not sure about the version of pinta.

Didn't had it in 12.10 till now.

[grofaty (grofaty)]

@Yinon-David-Zadok, you can check the installed Pinta version on your system by using Pinta's menu Help | About and there is Version number on About Pinta tab.

General info about default versions of Pinta in Ubuntu:
============================
Ubuntu 12.04 LTS: Pinta 1.1
Ubuntu 12.10: Pinta 1.3
Ubuntu 13.04: Pinta 1.3
Note: Above default versions can be checked by: http://packages.ubuntu.com/
============================

You can add more current Pinta version by adding Pinta stable or Pinta daily build to your system by using terminal.

1. Adding Pinta 1.4 stable repository:
sudo add-apt-repository ppa:pinta-maintainers/pinta-stable
sudo apt-get update
sudo apt-get upgrade

2. Adding Pinta 1.5 daily build (little bit unstable)
sudo add-apt-repository ppa:pinta-maintainers/pinta-daily
sudo apt-get update
sudo apt-get upgrade

Can you please test on one of this two PPAs and report back if the problem still appears.
