It seems there is a bug in the picture finder plugin. When I open an "Artists" (note: not "Artist") tab in a filter pane, right click and choose "search for a picture on internet", the following occurs:

- the name of the artist in the search field is always "1"
- i correct the artist name, and choose a picture from the new search results
- in the "save as" dialog, the check box at the bottom says "Use this picture for artist 'ARRAY(0xd8a9f7)'"
- When I click OK, the memory usage of GMB boosts up to 1.1GB! (And the picture is set correctly.)

I guess the easy solution to this problem is to disable the option to search for a picture in the "Artists"-pane...
