I'm taking over as the lzo maintainer in FE. So, I went and searched for all open bugs on it, clicked "change several bugs at once", chose "reassign bugs to" and entered my email to the corresponding text field, clicked "save changes", and got: Bugs Not Changed Um, you apparently did not change anything on the selected bugs. Well, um, I did try to reassign them. They were previously assigned to anvil, and they should have been changed to be assigned to me.
Ugh, this is a pretty serious bug IMHO.
A simple workaround for this is to add a comment when reassigning.
We are researching a solution for this problem.
