I've experienced several crashes bot reproducible and not so reproducible with 1.3.3. I think ver. 1.3.2 was pretty stable compared to this one.
Perhaps it's best for the Gnucleus dev. team to stop including new features and start to look at all the bugs in the next releases? If I try to run 1.3.3 for more than two hours it is aproximately 99% sure that it crashes while downloading.

Don't get me wrong. I think your product is looking promising and hope to use it full time in the future. In the mean time I have to run Bearshare 2.2.5(without the spyware). If it wasn't for the bugs I would definetely go for Gnucleus since I like the features allready included. One of the features I like best is the ability to choose which IPs to download from whenever there is available more than 1 copies of the file.

Good luck with future developement.
