[ubuntu-mono] [Bug 68479] Crash when slide-show over non-existing images

[Marcus Dapp]

Public bug reported:

Binary package hint: f-spot

- 3 images in total in an f-spot installation (v0.1.11) under Dapper Drake.
- Deleted all images from the ~/Photo folder outside from f-spot.
- Launch f-spot and start slideshow with View | Slideshow.
- Instead of first image a white square with a "?" is shown.
- On loading the second image, error message appears (see below)
- After a few seconds error message and al lf-spot windows close.
- crashed.
This is 100% reproducable.

First lines of error message (did not let me copy/paste all of it):

An unhandled exception was thrown: Object reference not set to an
instance of an object
