Leaving out the target for ctl:ruleRemoveTargetById causes segmentation faults.
This has already been reported and fixed for ctl:ruleRemoveTargetByTag: #1353.
My guess is that ctl:ruleRemoveTargetByMsg is affected as well but I did not test this.
Steps to reproduce the behavior:
Add a rule exclusion containing ctl:ruleRemoveTargetById=941130 instead of ctl:ruleRemoveTargetById=941130;ARGS:xxxx
