This problem was reported against Fusebox 5.1
The issue is that there is insufficient Source Code Lookup data for FusionDebug to accurately place the breakpoint.
Often, the addition of a Source Code Lookup in the debug launch configuration tab is sufficient to get breakpoints firing reliably.
More help on getting breakpoints firing can be found in technotes below.
