There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
PC-BSD® Bug Reporting/9.2
(Sorry for the inconvenience)
Beginning with PC-BSD® 9.2, a bug reporting tool is available in Control Panel. This tool can be used to easily send a bug report to the development team responsible for the software which produced the bug.
To access this tool, go to Control Panel ➜ PC-BSD Bug Reporting or type pc-bugreport from the command line. The initial screen for this tool is shown in Figure 8.20a.
Figure 8.20a: PC-BSD® Bug Reporting Utility
Select the software component that most closely matches where the bug occurs. For example, if the bug occurs when using a KDE utility, select "Desktop environment", or if the bug occurs when using an application that was installed using AppCafe®, select "PC-BSD software (pbi)". When in doubt, select "PC-BSD base system".
In the example shown in Figure 8.20b, the user has selected "PC-BSD base system" then "Next".
NOTE: regardless of the selection, the resulting screen will be similar to 8.20b. The various screens only differ in which bug tracking system or mailing list is used by the development team for that component. If you select "Desktop environment" you will also be asked to indicate which desktop so that the correct information is displayed for that development team. Similarly, if you select "PBI software" you will be asked to select which PBI produces the error.
