Version:           0.9.2-svn (using 4.1.66 (KDE 4.1.66 (KDE 4.2 >= 20080912)), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.25-gentoo-r7

Steps to reproduce:

1) run 'parley practice'
2) See the error message "The vocabulary document contains no entries that can be used for the chosen type of practice."
3) Click "ok"
4) Click "ok" on the practice summary (the first click just brings up the same widget again)
5) See parley (recent svn checkout) crash after the second click with the backtrace below:

Remark: I never started parley before, so I especially have no vocabulary document set.

Application: Parley (parley), signal SIGSEGV
