Incorrect image size reported when using Tools->Resize Image

[schneeland]

Binary package hint: gthumb

When using the latest version of gthumb on Ubuntu 10.04 LTS (installed via webupd8 PPA), it reports the image size inccorectly as 2 pixels or 2% when trying to resize it via Tools->Resize Image.

Strangely, it still works when using the "easel"-symbol on the right to show the editing pane and subsequently moving to the respective image resizing screen.

Also, it has worked before, but seems to be broken since one of the more recent updates (sorry for not being more precise - I use and maintain this computer every couple of months when I visit my parents).
