[openbeos] input_server filter issue

I have been working on an input server filter for ScreenSaver. The general
gist of it is that we add a BMessageRunner to the input_server. It's job is
to post a message to the Input Server every N seconds (where N is what you
set in the screen saver preferences app). A BMessageFilter catches that
message and calls a function checking to see if keys were hit and, if not, to
invoke screensaver.
Now, I am sure that I have done something dumb... But my problem is that when
I create a BMessageFilter and call be_app->AddFilter(filter);
At that point, the Input Server crashes. So, obviously, I can't do a whole
lot of debugging.
I can verify that be_app seems to be valid (and it should be). I can't think
of any reason that this should fail.
Here is the relevant code:
SSISFilter::SSISFilter() : enabled(false) {
pref.LoadSettings();
blank=pref.GetBlankCorner();
keep=pref.GetNeverBlankCorner();
timeMsg=new BMessage(timeUp);
runner=new BMessageRunner(be_app_messenger, timeMsg, pref.BlankTime()
*1000000,-1);
filter=new BMessageFilter(timeUp,timeUpFunc);
be_app->AddFilter(filter);
}
I am open to thoughts and ideas...
