I am also new to swish-e -- but I have years of experience with the
original swish, so this could be the answer:

We used to find that swish would crash as you describe -- and it turned
out to be that we were trying to index some kind of binary file -- .bin,
.exe, .sit etc.

To fix that, make sure that your config file excludes those file types,
e.g.

  FileRules filename contains .tiff .gif .jpg .hqx .sit .bin .exe
