It's indeed ironic...ACRA crashes during initialization, then crashes again while trying to report its own crash.
I have decompiled Wifi Protector and found out that it's using a very old version of ACRA. Have a look at this issue: https://code.google.com/p/acra/issues/detail?id=138
It was fixed
in October 2012 and prevented crashes that could occur if one of the fields in the Configuration is null.
If this has started to happen recently (on or after Jun 30), it's likely the same root cause described here: http://forum.xda-developers.com/xpos...posed-t2803025
(but again, the main bug is in the old version of ACRA)
