I'm sorry, my mistake.

The installed PHP extensions linking against libkeyutils-1.2.so on my
system are imap.so (package php5-imap 5.2.6.dfsg.1-1+lenny3),
pdo_pgsql.so and pgsql.so (both package php5-pgsql 5.2.6.dfsg.1-1+lenny3).
The installed PHP extensions linking against libXdmcp.so on my system
are gd.so (package php5-gd 5.2.6.dfsg.1-1+lenny3) and imagick.so
(package php5-imagick 2.1.1RC1-1).
No custom or locally built extensions are being used.

Given I can reproduce such a segfalut, how do I generate backtraces best
on a system being used by customers?
