Free bug tracker with desktop client?

I'm looking for a free bug/issue tracking system that has a desktop client.

It can run on any server type that doesn't require SSH/RemoteDesktop or be hosted
Client should run on windows.
And it needs to support more then 1 developer

Does anyone know of something like this, if there is have you used it and how did it work for you?

From stackoverflow

• I just found Gemini which allows up to 5 users. I havn't used it (yet?) but it looks good so far.

• A certain numbers of desktop clients are available for Bugzilla, you can find a list there. The only one I tried is Deskzilla (support Mac OS X), but I just like the web version so i don't use it

  Unkwntech : Nice, with one of those (I'm gonna' check out beskzilla), I'll probably use bugzilla, I prefer not to be tied to windows servers after all.
