I noticed log files e.g. 'tracker0.log' currently include userdata used for accessing the bugzilla server e.g
20050822-morenumbers INFO POST http://example.bugzilla.org
20050822-morenumbers INFO Bugzilla_login = example@mail.com
20050822-morenumbers INFO Bugzilla_password = ishere
20050822-morenumbers INFO GoAheadAndLogIn = 1
20050822-morenumbers INFO GoAheadAndLogIn = Login
Admittedly this probably wouldn't be seen as an issue by everyone since Deskzilla log files're on the local machine and... the workstation should ideally be secure anyway.
I can see how some users more familiar with only seeing asterisks or other characters/hashes instead of login details, within application log/settings files might be uncomfortable though. Less visible userdata might be preferable.
