The folks at irc://freenode/gtk-gnutella helped me solve a problem where I was not getting any search results. I'll post the solution here because this forum seems to be a cental location for troubleshooting.

The problem was that I was not getting any search results, no matter what I searched for.

I started gtk-gnutella from a command prompt, turned on Search debugging, and found that every time I executed a search, a message went to the console saying something to the effect of «Discarding invalid empty search ""».

The problem was that I configured for extended nonlatin character support, or ICU. I reconfigured and recompiled, and the problem was fixed.

When you run Configure, remove "-licuuc" from the propt that asks which libraries you want to link to.

My version of the ICU library is 2.6-94, and it is yet unknown if this was a specific bug with that version of the library.

Any comments or clarifications by people who know this program better than I do are welcome.
