Crash when editing composer name in "Composer" window [#15829]

[gamb2009]

When you try to edit the name of a composer in the "Composer" window, most of the time MM5 crashes and/or freezes.

See link for image. MM5 has crashed without being able to send an error report.

It seems that it happens when two pictures of the same artist are shown, for instance one misspelled, the other correctly written and, after the editing of the wrong name, MM5 tries to fuse both images into one and... crash!

Thanks, I was able to find exact steps, how to reproduce this quite consistently, tracked as: https://www.ventismedia.com/mantis/view.php?id=15829
