Public bug reported: A bug in libclucene0 that was fixed [1] long ago causes strigicmd to crash.
It would be best to update to the latest stable release (0.9.21b) but adding the patch below suffices too. The crash (segmentation fault) can be obtained by running e.g. mkdir /tmp/clucene valgrind strigicmd create -t clucene -j 1 -d /tmp/clucene $HOME It might take a while for the crash to happens which is why running with valgrind is good: it shows the memory corruption [3] quickly. This problem exists in jaunty and karmic [2].
