DotNetNuke Gallery

Today, I have been trying to find a problem in DotNetNuke. When users navigate to certain page, they get something like:

A critical error has occurred.Object reference not set to an instance of an object.

After a considerable time spent trying to look for the problem, finally found the EventLog table, in which I find that the problem is with Gallery Module. It throws an ArgumentException:
Path cannot be the empty string or all whitespace at the
DotNetNuke.Modules.Gallery.GalleryFolder.Populate. Nice event log, at least.

Finally, I found that bug described at http://support.dotnetnuke.com/issue/ViewIssue.aspx?id=1507.

Looks like they're not fixing it. Don't know why.

Anyone know of an alternative image gallery for DotNetNuke?

Thanks a lot
