Just to clarify (since cheetah doesn't give us good traces) the issue occurs inside the printValue function that is defined inside the taskinfo template. It has this stanza

  #elif $key in ('build_target', 'target_info')
<a href="buildtargetinfo?targetID=$value['id']">$value['name']</a>

This function is used to print the task parameters. The code is assuming that either of these keys will map to a dictionary. The existing code replaces 'target' and 'build_target' parameters with a sanitized built_target parameter that is a dict, however prior to this PR it did not do this for target_info even though printValue seems to expect this.

See also: PR #3455

At any rate, this fix is fine, though I think it ensures that printValue will never encounter a target_info key.
