This issue should be fixed in trunk. In a mean time you should be able
workaround that by deleting
<workspace>\.metadata\.plugins\org.maven.ide.eclipse folder.

I've made a "custom Eclipse distro", which is basically Eclipse "JEE package"
3.3.1 + Subclipse and m2eclipse 0.0.11.20070916-2300
We're using Windows XP SP2 and Sun Java 1.6.0_02
On my machine, it works fine, but on a colleague's machine, m2eclipse wont't
initialize properly, with the following error:
org.eclipse.core.runtime.CoreException: Plug-in org.maven.ide.eclipse was
