"seed_monitor_on()" globally changes handling of severity Error by use of "set_actions()"

My SystemC-Code is using messages of severity "Error" to intentionally throw exceptions. Suddenly I realize that no longer exceptions are thrown. Analyzing this issue, I targeted the function in my code "scv_random::seed_monitor_on(true, "../../Source/seedfile.txt");" to be the cause of this. For my current scenario I screwed up the path to the "seedfile.txt" which results in an error in "seed_monitor_on()". In this "seed_monitor_on()" calls the following:
  cannot_open_seed_file() -> message() -> set_actions(SCV_ERROR,SCV_LOG|SCV_DISPLAY|SCV_CACHE_REPORT)
 
Conclusion at it seems to me: In case of a file not found "seed_monitor_on()" removes throwing off exception ("SC_THROW") in ALL(!) cases of messages with severity "Error". I would consider this to be an unwanted global side effect and probably a bug. Or?
