it's definitely wrong. there are some bugs on file handling in rc7 and that might be your problem. Do the following:
mv ~/.aMule ~/.aMule2 && mv ~/.eMule ~/.eMule2 && amule
let's see if aMule stats now.
If it does, please DO NOT delete those files and directories moved above for two reasons:
1) they contain your downloads, your data and your config
2) we need it to see what was failing and check if it fails too on current aMule CVS
so, once you checked that it works, report here and we'll tell you what's next to do

Greetings!
