Description of problem:
Steps to Reproduce:
1. Select the Tasks list
2. Attempt to add a new task to the list

Selecting the date box brings up the date selector, and allows a date to be selected, but any attempt to enter the date leaves the date box blank. Typing a date into the box also leaves the date box blank when Enter or TAB have been hit.
After a few tries Evolution crashes.

Similarly, entering the task description first and then clicking the date box immediately wipes out the description. I can't say definitely if this also causes a crash. However, I've seen several crashes I *know* were related to trying to enter a date.

Version-Release number of selected component:
evolution-3.16.4-2.fc22
