Hit Count for breakpoint does not work

1. Hit a breakpoint.
2. Right-click into the Breakpoints view and select "Use Tooltips..." from the context menu.
3. Hover the mouse pointer over the breakpoint from step 1.
   In the appearing tooltip you can read "Hit Count: 0".

We just hit this breakpoint, so this number should be greater than 0. When using gdb, this works correctly.
