Package: citadel-server
Version: 902-3
Severity: grave
Hello,
I have confirmed this issue in both stretch and sid with version 902-3. jessie with version
8.24-1+b3 is fine.
Essentially, I can neither log in with the admin account nor create a new user.
This also occurs if I make the attempt via webcit. It results in citserver
segfaulting.
I am ataching a script output from gdb showing a backtrace from both attempts:
first the attempt to register a new user, and then an attempt to log in to the
admin account.
I am also showing script output from the citadel client on this.
