I am using Ubuntu 11.04 Desktop and when I right click on a particular folder and select "Open With Other Application….", some of the applications are repeated multiple times. This is happening with more than one application. I was able to get rid of them from the "Edit Menu" option, but why does this happen and how to make sure it doesn't happen again?

As to why it happens, I'm not 100% sure. Sometimes it happens with WINE applications due to some difficulties in setting up the .desktop files and the appropriate associations.
It is a known problem however, and it hopefully should be fixed in the near future.
To solve the problem for yourself, remove the duplicate entries in:
~/.local/share/applications, and it should be fine. Most of the time when you do this once you won't have to do it again until you reinstall the application in question.
