i added --spec format to the bottom of my spec.opts so it looks like
this
--colour
--format progress
--loadby mtime
--reverse
--spec format

i'm not sure if this is what you meant. i did a quick search on google
for some documentation on this file but didn't find anything.
anyway, now i am not getting the segmentation fault but "0 examples, 0
failures" so i think i'm doing something wrong.

>> rake spec:rcov --trace
(in C:/Documents and Settings/Scott/My Documents/NetBeansProjects/
blog)
** Invoke spec:rcov (first_time)
** Invoke spec:clobber_rcov (first_time)
** Execute spec:clobber_rcov
** Execute spec:rcov
Finished in 1.594 seconds
0 examples, 0 failures
