java.nio.Buffer exception

About 25% of the time I start IDEA, I'll see the exception below.  The only way I seem to be able to recover is by shutting down and restarting, which triggers a lengthy re-indexing process.


I'm running Ubuntu 10.10 (but it also happened frequently on 10.04), 64bit.  Please let me know what, if any, other details might be helpful.
