Pinta 1.6 unhandled exception error after install.

[Nina T]

STEPS: Download and Install new version Pinta 1.6 on Max OS X Yosemite version 10.10.2 Mac mini server (late 2012). Unzip and copy Pinta icon to applications folder. Below error appears. Click OK. Pinta closes. Also downloaded and installed Mono after that. No change.

I think this might be an issue with the Mac package being built on Ubuntu, which uses a newer version of Mono.Cairo than what is shipped with the Mono installer we link to from http://pinta-project.com/releases.

Can you try out the latest Mono installer from http://www.mono-project.com/download/ and check if that works?

Regardless, though, I think https://github.com/PintaProject/Pinta/commit/34b698d3 needs to be changed to use a separate method rather than an extension method in order to avoid this problem.

It worked. That was the problem. No more errors. THANK YOU!

OK, good to hear! We probably should have updated to a more recent version on OSX anyways, so I've updated the website to recommend that version (https://github.com/PintaProject/website/commit/09983084).

For Pinta 1.7, we should still fix the issue I mentioned in my previous comment.

Cameron, it looks like this new download link is now broken. In browser: http://www.pinta-project.com/releases and click on "Mono OS X (Required)" At the end of URL link it is (without double quotes): "target=". If this " target=" is deleted from URL then download starts successfully.

[grofaty (grofaty)]

Now I see it current link:
[some text] xamarin.x86.pkg target=

there is missing double quote characters after 'pkg' like this:
[some text] xamarin.x86.pkg" target=

[Cameron White (cameronwhite91)]

Thanks, it should be fixed now (or whenever the website next pulls in the changes from Github)

[Cameron White (cameronwhite91)]

I don't think this will be a release blocker for 1.7, since the Mac installer is now built on OSX instead of being cross-compiled from Ubuntu. Tagging this as a GTK3 issue since the whole SetSource() issue will be something that can be removed in the GTK# port.

[Cameron White (cameronwhite91)]

The remaining issue was fixed in the GTK3 branch of Pinta
