Yes - it seems to be a molly brown bug.

If you take a valid URL that references a folder not having a trailing 
slash, and add a query to it, molly brown goes off on an endless redirect.

For example, try this one:


1. Here the "capcom" folder exists with an index.gmi therein
2. Molly brown thereby puts a slash on the end of the URL, but what it 
should do is put a slash after the capcom maybe, thus




in this second case, molly brown will redirect again to


and so on.

I'll let solderpunk know.

In the mean time, I suggest not to construct strange parameterised URLs 
to folder URLs on molly brown!
