Now working.

Try to reproduce:

[nic@albert ~]$ sudo urpme hamster
The following packages contain hamster: 
hamster-time-tracker-2.0-0.rc1.3.mga6.noarch
xfce4-hamster-plugin-1.6.1-2.mga6.x86_64
[nic@albert ~]$ sudo urpme hamster-time-tracker
To satisfy dependencies, the following 2 packages will be removed (2.3MB):
  hamster-time-tracker-2.0-0.rc1.3.mga6.noarch
  xfce4-hamster-plugin-1.6.1-2.mga6.x86_64
   (due to missing hamster-time-tracker)
