This issue is related to the tracker service.

Example: <a href="/tracker/index.php?func=detail&aid=94&group_id=5&atid=101">Viewcvs chokes
on some projects' RCS files</a>

At fact i have some trouble using myLar plugin (it can't cast links to the correct URL). i have done small research
and can say that trouble is in "&".

Does "&" symbol can be changed to "&amp;"?
