This is not just you a lot of others have had similar issues. One of which is that it will allow you to do a multi-select of none or null and another value. when this get to the DB it errors and then there go your columns and view selections and everything. The post from 5.7FSN I believe is correct but the syntax was a bit off and if the view still errors or you cannot remove it there are a few more steps.
Look at the URL and if it has a question mark after the ".jsp"
Then add this to the end of the URL "&resetParams=YES" without the quotes.
If you do not have a question mark after the ".jsp"
Then add the "?resetParams=YES" again without the quotes to the end of it.
Explanation of the above:
The question mark denotes the start of parameter value pairs being passed in the URL which are separated by ampersands.
So you could have a URL like this "http://YourNameHere/HelpDesk.jsp?Parameter1Name=Parameter1Value&Parameter2Name=Parameter2Value"
If the view displays then remove the offending filter or filter selections and then browse away from that list page and back to it again without the "resetParams=YES".
Your problem may be solved here if it is not then continue to read.
From what I remember from support the last time happened to us we did the above and when we were able to view the list again we then had to remove the filter and the column that was filtered. Then browse away from that list and then back again without the "resetParams=YES" to make sure the issue is gone then add the column back along with any filters that were applied.
If that does not work then you may want to get with support as they would be the only ones to help you from there.
