Scrolling blocks the rest of the GUI, may have caused system freeze.

I started a big scrolling operation with the mouse wheel in the Downloads panel, then switched to another workspace. When I came back, the list box was not done scrolling, and nothing else in Nicotine could update or redraw itself. When the scrolling was finished, the whole system froze and the music started skipping. So, I rebooted. This has only froze the system once, but Nicotine always blocks while scrolling. I suspect this is a problem with a GUI lib, not nicotine, but I'm not sure so you get the bug report. I'm on an Acer Aspire 3050 laptop with the latest updates for Ubuntu 8.04.1.
