I know, there were posts before here on SO before concerning issue or bug tracking systems, like this one, but the given answers point either to commercial systems or web-based systems, which both seem to be oversized for our needs.

What I am looking for is a non-commercial tool for a team of 3 to 4 developers, which can be used on an existing fileserver, without the need of installing additional server software like a C/S database or a web server.

Some things I expect from such a system:

• allows to remember bugs (with a priority) and issues / ideas for new features (mostly without a priority)
• description of the issue, perhaps some additional remarks
• short info who entered the bug/issue entry
• one or more tags allowing us to group or filter the list

Any suggestions?

EDIT: I should have said that, but we are using MS Windows clients, Visual Studio development, Tortoise SVN (the latter works fine without a subversion server). And yes, I am strict on "no server software", since all server based solutions I have seen so far seem much to oversized/heavy weighted/too-much-effort-to-be-worth-it. In fact, if no one has a better idea, we are going to use a spreadsheet, but I can't believe there are no ready-made, light weight solutions.
