During netbeans startup right after a fresh install of NetBeans6 m10 got the exception below. Closed error window and
then NB would still run OK, just froze up for awhile. 

Appears to be Ruby plugin. Disabled Ruby plugin and that stopped the exception. Could be a permission problem but I have
a standard umask 022. Installed as root of course. Have not had problems before on NB 5.0, 5.5, and 5.5.1.

System:
JDK1.5.0_12
Slackware 11 standard install, nothing odd
NB 6.0m10
