[log4perl-devel] Can't call method "PRINT" on an undefined value

[Tony B. <log...@tm...>]

I'm getting a strange test failure in our framework on one machine and
not on another:

Can't call method "PRINT" on an undefined value at 
  /usr/share/perl5/Log/Log4perl/Appender/Screen.pm line 27.

Both machines have the latest log4perl, and major difference is that
the machine that's fine is perl 5.8.1 and the one that's not is perl
5.8.2. However I have no idea whether that's relevant or not, or whether
something else is going on.

At this point I can't get a simple failing test case: the error messages
don't even point me sensibly to where the problem is, and putting some
debug messages make the error report itself as happening somewhere
completely differently.

Before I go mad digging into this, has anyone seen this, or have any
ideas what it could be?

Thanks,

Tony
