git annotation view is missing the actual commit message

Binary package hint: kdevelop

When i enable the git annotation view on a source file a get a color coded bar with all the commits on the left of my editor.
When i hover the mouse over parts of the bar i get a tool top giving me additional information. Author, Date and Commit Message.
The Commit Message is always empty (even though there are commit messages).
