Got Sick
Two problems had been dogging my Gentoo installation recently: my Firefox (1.5.0.8) would freeze reliably on certain web pages, but not all. I eventually traced the problem to two old Flash plugins that weren't part of an emerge still on my system. I renamed them to something innocuous and the problem went away: /usr/lib/nsbrowser/plugins/flashplayer.xpt and /usr/lib/nsbrowser/plugins/libflashplayer.so
The other problem was that my copy of Gaim (1.5.0) would crash with a memory or pointer problem whenever I ran it. This I was able to solve by deleting the "block" lines from my ~/.gaim/blist.xml file.
Anyone else out there still using Linux or have you all moved to OS X?
