I found an issue when defining special rules for extensions in Configure - Folders - (V) Except for specific file types - Specify extension and target folder.
Let's say we have two rules: for *.tar.bz2 and for kde*4*.tar.bz2 in File Extension column, two different folders. As I've found out, the second works only if it is placed higher than the first. But this order is valid only till the restart of KGet. After restart the list is somehow sorted and more complex regexps are at the bottom and so they don't work.

To reproduce:
1. Enter *.tar.bz2 for  $HOME/1 folder and kde*4*.tar.bz2 for $HOME/2 folder.
2. Place the second string above the first.
3. Try to download 2 packages, one is random and another of some KDE4 source.
4. See everything works.
5. Exit KGet.
6. Try step 3 another time.
7. See the second string doesn't work.
8. Open Configure - Folders and mention that kde*4*.tar.bz2 string is below the *.tar.bz2.
