Duplicate Symbol Error in Objective-C build?

Question

I got this error when I press build+debug:

ld: duplicate symbol .objc_class_name_BlogTableItemCell in /Users/fabian/Development/Workspaces/iphone_experiments

I just ran into this problem myself. For the list, here's another possibility:

Duplicated linking line in the project file.

I caused this merging conflicts on a SVN update, when I accidentally duplicated a line.
