renaming folder with with date in name gThumb doesn't work too well

Binary package hint: gthumb

Original name:

ie:
~/tmp/foldertest$ ls
2010.10-1

test 1:
Edit name with gThumb by replacing "-1" with ".01":
result:
~/tmp/foldertest$ ls
2010.10.01.10-1

test 2:
Edit name with gThumb by removing "-1":
result:
2010.10.10-1

test 3:
let's have a bit longer name
~/tmp/foldertest$ ls
2010.10-1 some test text

remove "-1":
result:
~/tmp/foldertest$ ls
2010.10 some test text.10-1%20some%20test%20text
