GRC attempts to read the doc string of each block during load. If the import of a block seg faults, so does GRC. If all you changed is install gr-cdma, that's probably the reason for GRC failing. Looks like your installation of gr-cdma is broken. FYI, moving the doc string extraction this into a separate process shifts this problem to runtime (when you execute a flowgraph with erroneous blocks). I hope have this merged soon.
