I have updated the last.fm packages for Debian sarge (1.0.7-0sarge2) and Ubuntu dapper (1.0.7-0dapper2). This update solves a bug that caused the program to segfault when double clicking on Friends.
Download them at http://people.igalia.com/berto.
Version 1.0.9.6 is not affected by this bug, so if you’re using Debian etch or Ubuntu edgy you don’t need to do anything.
Happy holidays.
