| Steps To Reproduce | add or delete a user from any channel | ||||
| Additional Information | services also appeared to crash after another user with a different nick tried to do a qop add ... this user was a founder. not sure if it was a founder related issue or not. | ||||

Fixed in f3f6727cdddf0a7e1e01311f9641a081885957d9 |
|
|
weird .. coz it was also affecting other users who aren't nick linked .. it also affected other levels like SOP as well |
|
|
Uploaded a backtrace from my own reproduction of the bug (bt_qop_crash). It appears that it happens when a user on the QOP list tries to manipulate the QOP list himself/herself. |
