Error messages when using GIMP AppImage PhotoFlow plugin

Using the latest GIMP AppImage I found following bugs:

To reproduce:

Open a raw file by right click in file manager on that file and select ‘open with GIMP AppImage’
=> GIMP starts, PhotoFlow plugin starts, fine.
Now close PhotoFlow plugin using the ‘x’
=> PhotoFlow plugin closes and GIMP shows this message

When closing PhotoFlow plugin using the ‘Cancel’ button instead of ‘x’ GIMP shows this message

Edit: I forgot to mention that it works fine when I use the ‘Ok’ button to close the PhotoFlow plugin

I submitted an issue not to forget about it: GIMP plug-in crashes when terminated with the window close button or the "cancel" button · Issue #109 · aferrero2707/PhotoFlow · GitHub

@heckflosse I found a proper fix for this issue, so next version of the appimage should work properly when cancelling the RAW loading.

Thanks!
