大概原因就是部分组件太新了。
貌似pidgin也有这种问题，gtk升级之后群就null了，所以我现在很痛苦，并且不想把gtk降级。
只有等新版pidgin出来了
problem:
yum installation of video/dvd related software stops with: Missing Dependency: libdvdread.so.3 is needed by package mplayer
solution:
there might be a conflicting version of libdvdread installed (for example because of previos VLC installation )
check that with:
[root@server heiko]# yum list libdvdread
Installed Packages
libdvdread.i386 4.1.1-3.fc9 installed
Available Packages
libdvdread.i386 0.9.7-3.fc8 fedora
deinstall is and re-install it:
[root@server heiko]# yum erase libdvdread
(attention, this might deinstall dependent software -e.g. VLC as well!)
…
Removed: libdvdread.i386 0:4.1.1-3.fc9
yum install libdvdread
Installed: libdvdread.i386 0:0.9.7-3.fc8
now install the video/dvdsoftware (e.g. mplayer/mplayer mozille/firefox plugin)
[root@server heiko]# yum install mplayerplug-in
…
Installed: mplayerplug-in.i386 0:3.45-2.lvn8
Dependency Installed: enca.i386 0:1.9-3.fc6 libdvdnav.i386 0:4.1.1-2.fc8 lzo.i386 0:2.02-3.fc8 mplayer.i386 0:1.0-0.88.rc2.lvn8
Complete!
Bingo !
