How to solve the following error when trying to delete a package from a Subversion-controlled directory in an Eclipse Project with Subclipse 1.2.4: “Thread attempted to read nesting count of a lock it did not own.”?

A workaround was to rename the containing project and the package (and perhaps the other packages in the project also), using the refactoring function of Eclipse for that. After that, deleting the package worked without problems. Restarting Eclipse was no workaround.
