Try do delete an existing user, you should see an error. The user does get
deleted though (but not from the groups, see related bug #194355).

I've tracked down the problem to this piece of code in editusers.cgi:

    SendSQL("DELETE FROM profiles
             WHERE login_name=" . SqlQuote($user));
    print "User deleted.<BR>\n";

The problem is that Bugzilla->logout_user_by_id() tries to get some user info
from the database, but it is called AFTER the user is deleted from the database.

Putting that statement before the SQL DELETE fixes the problem. While you're at
it, you also might add another DELETE statements to clear the groups properly,
so the resulting code should be something like this:

    SendSQL("DELETE FROM profiles
             WHERE login_name=" . SqlQuote($user));
    SendSQL("DELETE FROM user_group_map
             WHERE user_id=" . $userid);
    print "User deleted.<BR>\n";

Reproducible: Always
Steps to Reproduce:
1. Create some user
2. Delete it

Actual Results:  
Deleting user
Software error:

Can't call method "id" on an undefined value at Bugzilla/Auth/ line 195.

For help, please send mail to the webmaster (, giving this error
message and the time and date of the error. 

Expected Results:  
Print "User deleted", with no errors.
I was going to go stick this to Future and assign it to nobody, since we've
officially stated many places that we don't really support deleting users (see for a good writeup on

However, since you've more or less provided the fix here, we might as well get
it in. :)  Are you comfortable enough with cvs diff to turn this into a patch?

Patch to delete a user semi-properly (only works for users with no bugs/comments)

Heheh, just read that article...

"If people want to do dumb stuff, they can write the code for it on their own

Well, guess what I just did :)

Attaching patch.

The patch in bug 119485 covers this.

This looks like the right thing to do, and no reason not to backport it to 2.18
as long as we have it.

No offence to Wurzlbap, but this was here first, so let's get it in this way so
Ivan gets credit. :)  I'm not comfortable with an entire templatization patch
going on 2.18, anyway, and this one can.
