Description of problem:
Xvnc crashes when running Eclipse 3.3 on rhel3.  Appears to happen relatively
randomly (usually within the debugging perspective) and is a blocker for us.

Version-Release number of selected component (if applicable):
vnc-4.0-0.beta4.1.4

How reproducible:
Frequent with this version of VNC.

Backtrace:
