Description of problem: Comments approximately larger than 2k are being blocked from going into the longdescs table. This works fine in the 2.17 prod bugzilla. Also a problem is no error is generated and the change seems to go in. This happens for both the new bug and edit bug comment fields. An example of a comment that would not go into the db unless using 2.17 is bug 142613. Version-Release number of selected component (if applicable): 2.18rc3 beta3
The problem is not with the size, but the content. Any comment with the string 'lock' in all caps will not get posted and no error will be reported.
Should be fixed now in CVS and current beta.
