Crash to a white page when editing properties

When I make changes to my properties values and save inside the Custom Properties Manager: Edit Property the component editor crash the administrator page to a white screen and I have to reopen the administrator in a new browser window...!!

I am running joomla 3.3 www.dropbox.com/s/t7ljxa8tusare7t/Screen...06-26%2015.44.43.png
and my custom property components seems uptodate ...

Thank you

Just downloaded the CP version 3.1.5 and the problem seems solved...

Good job.
