IllegalArgumentException in SearchBar

[slumdroid]

WikiCFP version used is 1.1.2 (the latest version on the market)
Application crashes with the following stack trace when I typed in SearchBar "2014 " (the last character in text is a "space"):

Application crashes if you enter a phrase that contains spaces, too...
such as "software engineering"
