Tickets in RT3.6.5 not correctoly displayed!


I noticed that some of our tickets are not correct rendered.
Long lines in ticket text are not wrapped and
running out the HTML Boxes.

Text buttons (Reply, COmment, Download) in the affected
correspondence transaction are also misplaced.
The rendering of the other correspondence in the
same ticket is not affected.

The problem seems to be triggered by extreme long URLs
(which have no spaces of course)
It seems reasonable not to wrap them, but
if you look at the output it looks broken.

best regards!
