Actually this seems to not be related to wpapsk format, john crashes
in formspring. Backtrace below:

$ ./john -fo=wpapsk wpapsk.txt
No password hashes loaded (see FAQ)

$ ./john wpapsk.txt
Segmentation fault

(gdb) run wpapsk.txt
Starting program: /home/ukasz/wpapsk_crash/JohnTheRipper/run/john wpapsk.txt
