I've got two things for you to try:

(1) Here's a new test version of Log::Log4perl, which will print "[undef]" if any expected return value of caller() is not defined, instead of the warning you're getting:
    http://log4perl.sourceforge.net/Log-Log4perl-0.28dev2.tar.gz

(2) The fact that you're getting undefined values seems to indicate that your Log::Log4perl::caller_depth variable is off. Did you modify it? If not, I would really like to track this down. Can you provide a short code sample with a signal handler and a function that reproduces the problem? Also, please make sure to read the FAQ dealing with a similar issue:

    http://log4perl.sourceforge.net/releases/Log-Log4perl/docs/html/Log/Log4perl/FAQ.html#how_can_i_make_sure_my_application_logs_a_message_when_it_dies_unexpectedly

Towards the end, it shows how to offset Log::Log4perl's caller stack to get the right subroutines/lines numbers in the pattern layout. 

Thanks for your help!
