Just found a nice bug:

If you change the skin in zimbra desktop, you cannot access it anymore (i get forwarded to a blank page: http://localhost:7633/public/skinError.jsp?skin=ttt)

Version: zdesktop_linux_x86_0_36
OS: Ubuntu 6.10

There seems to be a bug report to this as a general zimbra behaviour, but none for zimbra desktop

Regards
