Actually, after some investigation I repeated the error and committed a fix.
If I set (on WinXP) HTTP_PROXY to a dummy variable I get the same error:
Can't use an undefined value as an ARRAY reference at
C:/Perl/lib/LWP/UserAgent.pm line 787.
It's EUtilities-specific as other WebAgents that have proxy settings do not
have the same problem, though I haven't checked any WebAgent-based classes.
I think this may also partly be an LWP bug as setting env_proxy to
TRUE/FALSE doesn't seem to have an effect, but instantiating with it
(env_proxy => 1) in the constructor fixes the problem. Anthony, I have
committed a fix to CVS to GenericWebDBI and EUtilities. Could you try it
