Unhandled error message when using "save as" on files outside the user directory

[PaulchenPlump]

When I open an image outside my user directory and then choose "save as" I get the following error message: 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. at Pinta.Actions.SaveDocumentImplmentationAction.SaveFileAs(Document document) at Pinta.Actions.SaveDocumentImplmentationAction.Activated(Object sender, DocumentCancelEventArgs e) at Pinta.Core.FileActions.RaiseSaveDocument(Document document, Boolean saveAs) at Pinta.Core.Document.Save(Boolean saveAs) at Pinta.Actions.SaveDocumentAsAction.Activated(Object sender, EventArgs e) at Pinta.Core.Command.<.ctor>b__33_0(Object o, ActivatedArgs args) at InvokeStub_ActivatedHandler.Invoke(Object, Object, IntPtr*) at System.Reflection.MethodInvoker.Invoke(Object obj, IntPtr* args, BindingFlags invokeAttr) --- End of inner exception stack trace --- at System.Reflection.MethodInvoker.Invoke(Object obj, IntPtr* args, BindingFlags invokeAttr) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.Delegate.DynamicInvokeImpl(Object[] args) at GLib.Signal.ClosureInvokedCB(Object o, ClosureInvokedArgs args) at GLib.SignalClosure.Invoke(ClosureInvokedArgs args) at GLib.SignalClosure.MarshalCallback(IntPtr raw_closure, IntPtr return_val, UInt32 n_param_vals, IntPtr param_values, IntPtr invocation_hint, IntPtr marshal_data)

Problem seems to be the pre-selected path of the sandbox in the format "/run/user//doc/". A simple "save" works though! Operating system is Debian 12 with flatpak in version 1.14.4 and pinta in 2.1.1!

Hope you can reproduce and fix it. Thanks in advance!

I was able to reproduce by opening a file from /tmp and then doing Save As. This probably requires a fix upstream in Pinta

From https://bugs.launchpad.net/pinta/+bug/2045441, this seems like it may be solved with newer versions of the XDG portals library
