Overriding Failsafe view does not work

Hello,

I am trying to override the failsafe view : can't allow to let users see the default failsafe view from elgg. I did like I did for any other view... I created a directory : mod/myPlugin/views/failsafe/page/ with a default.php in it to override the elgg/views/failsafe/page/default.php from elgg. But it is not taken into account for an unknown reason. I'm on elgg 1.8. No cache, nothing. And yet, it's always the default.php from elgg that is taken... why? I even tried to copy/paste the file from elgg, and just echo "hello" in the title instead, didn't work either... I've tried everything... is it rly overridable? 

I'm asking you before I simply register another exception handler... and use a new layout for it.
