I need some help to discover to tell if I have found a bug or not in the UQM 0.5...
I went to Beta Pegasi on 039.5 : 745.8.
There I found a Rainbow World. Approached, Scanned and Launched a lander.
I've decided to go to Beta Pegasi with just on right Fuel. 70 units. I could go, discover the planet. When I should go back, I would run out of fuel, and a Melnorme Trader should find me.
OK, Indeed the Melnorme trader found me. But I COULD NOT SELL HIM the information about the Rainbow planet.
Assuming you didn't load in between, it does indeed sound like a bug. I suggest you post it at our bug database, and attach your save game. One of us will look at it, one of these days.

Okay, I tried it. Left starbase with 62 units fuel. Got to Beta Pegasi, looked at the first planet (didn't even have to send the lander), returned out of the system, and ran out my fuel.
Mr. Black the Melnorme offered to buy my rainbow planet information.
So my guess would be that dude already visited there.
