The issue SEL-116 has been resolved (in the 0.5 release), so the fixes should be in the latest code.
Patches can be applied by using Subversion. If you are using TortoiseSVN there is a 'TortoiseSVN -> Apply Patch menu', which you can use. The patches you mention would not be able to be applied as the source code has changed significantly since then.
If you are still experiencing the problems mentioned in this issue (with the latest code), maybe you can re-open it and add some details.
