Bug Description

Using Xubuntu 11.10 with gnome (3) and kde libraries both installed. I imagine I'm missing some dependancies?
Upon selecting eyedropper tool, the following exception repeatedly shows:

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

Still the same thing, I think it might be a GTK dependency version problem,
or where Xubuntu stores a file (I see some indication some are "missing"
but they just might be in a different folder due to Xubuntu 11.10 using
LXDE and not XFCE as I had thought?)
Synaptic is showing no broken packages, and all the latest versions but who
knows. Might be a bug in the Gnome libraries?
My system is fairly complicated, as I've installed both Gnome and KDE on
it, as I went a little nuts installing "this and that" not in the original
packages, (when it should be using either XFCE or LXDE, from what I
understand.) It's definitely not a standard 'buntu, so things are likely
not to be perfect.
Might re-install Pinta and see what happens.
I'm fairly new at this so, no ideas besides those.
Thanks!

Yes, I think reinstall might be your best bet right now. Is it really only the eyedropper where this happens?

Yes, just the eyedropper. I wonder if it has something to do with the way I
have transparencies set up. I usually have a window open underneath.
Haven't checked it, been busy with other things.

Same thing, after upgrading to 1.1 (Tried re-install, that didn't do a thing.) Same errors.
This happens EVERY time eyedropper is selected and then the cursor is moved to the canvas. When dismissing the error message it re-occurs if the cursor is still over the canvas when the error message is dismissed. Moving the close button off the canvas and then closing will not bring about the error. If another tool is then selected, the error doesn't re-occur, until the eyedropper is re-selected.
(seems strange that dll's and an exe are used in linux... but I'm sure that's been accounted for.)
Oh well, no eydropper selection if I use Pinta, for now.
Thanks.

Technical note: Pinta.Core.GdkExtensions.Invalidate (Gdk.Window w) is a static method that expects to operate on a GDK window, but for some reason it doesn't appear. Could be a result of unusual desktop effects, but that does seem a bit far-fetched.

System is Xubuntu with KDE and Gnome libraries enabled. Currently on 11.10.
Mine is highly customized, I'm sure that has something to do with it.
I'm still a bit of a newbie so if you want to tell me how to send some sort
of system report, I could do that. I know it's quite possible to muck
things up by removing dependencies and adding odd programs, like I have
done. Synaptic shows no broken packages or missing dependencies but who
knows? It might be that some of them are installed but are not working
correctly, say, something to do with "what file opens the color picker in
Pinta." and the system doesn't have a clue.

I'm curious to know if the angle picker widget (used in the Rotate/Zoom Layer dialog) and the color gradient widget (used in the Adjustments/Levels dialog) also have these errors for you.

They both make the same call to GdkWindow.Invalidate() that appears in the crash report.

OK, thank you for looking into it, will see if I can apply the fix soon. I
bet that really required some tracking down.
Can I assume just it's just a matter of finding the indicated file replace
it with the new .cs file, or simply modify the indicated lines in my
current copy of the file in a text editor? As I said in previous replies,
I'm still a bit of a Linux newbie.
Also, I'm currently on another machine on another OS and will have to boot
the affected machine to apply the fix. Or, should I see if there is a new
version in the repositories and re-install or update?

OK thanks a lot. I don't have it installed on this XP machine, nor do I
have a clue how to do that. It's not real obvious from the website other
than installing the gtk first with the .msi (Lazy windows user here, I'm
afraid.) I wasn't even aware it was available for Windows 'til just now,
but then again I use paint.net on my XP machine all the time, instead.

Fixitman,
Instructions about installing Pinta at: http://www.pinta-project.com/HowTo.Installing-Pinta.ashx

To add daily build see "Pinta repository" chapter in above link, but in first command replace word pinta-stable with pinta-daily
P.S. Because this fix was done today, fix will be available in tomorrow's update.

If you would like to try out how to compile from source (nothing difficult!) in the same link as above follow chapter "Using Github".

for Pinta 1.2 on Windows you can download stable version from http://www.pinta-project.com/download.ashx
1. Download/install .Net v4 (see above link)
2. Download/install Gtk# for Windows
3. Download/install Pinta

You can also install Pinta 1.3 development preview (development preview for Windows is one a week!):

The 1.3 fix works great! It took some doing to remember how to install,
though, (I wound up installing the .deb package with Gdebi, instead of
Synaptic, which I normally use but it didn't like the package for some
reason.)
Doing it that way, i had to fix a dependency issue, however.
The new version is great, no error on the eyedropper (with color palette
minimized.)
 Speaking of, I was having trouble with the way the tool windows (Palette,
toolbox, layers etc.) operate, it seems they want to default to
docking/pinning and then hiding themselves. I'm much more used to floating
toolbars that don't hide themselves every time you move them, OR always
visible fixed toolbars for them. (No, I'm not a big fan of Gimp, but being
able to move helper windows outside the active window kind of grew on me
over the years.) Seems to me, you could have floating tools and then some
small buttons on a toolbar up top to access them quickly. To me it's
annoying how they automatically dock and then hide themselves if you move
them wrong. I finally figured out, how to undock them, and un-minimize
them. That was part of the problem with my reported bug I suppose.
 I'm guessing that was a problem with one in a million users, though!
I can see where some people would see the autodock/hide as a feature,
instead of a bug, however.
