fusesmb.cache crashes with double-free or corruption

[rickyrockrat]

Binary package hint: fusesmb

fusesmb does not work on Lucid 10.04 (mounts, but no data, and fusesmb.cache not running)
The fusesmb.cache.pid file gets created but that is all.
libc, libsmbclient, and fusesmb are current as of Wed Nov 10 13:48:21 MST 2010
