Fix a reflection problem with EventHandler
At least, I try to fix the problem described in #302.... It's hard to be
sure that it will be fixed. I change some calls so that EventHandler
works directly with the method names rather than with properties and
getters. It still works for me, I hope it will work on the installations
where it was broken...
