This is super-easy to reproduce and I assume it's because the "jump to problem" is looking for the trap, which no longer exists.
(Step 0: Be kind of dumb, like myself. Not strictly required but it helps.)
Step 1: Place any spike trap.
Step 2: Place a workstation such that the work spot is on the trap.
Step 3: Have someone go there to work until the trap is sprung.
Step 4: Open the alert envelope. "Jump to problem" does nothing.
