Package: libapache2-mod-ruid2
Version: 0.9.8-3
Severity: grave
Dear Maintainer,
I'm trying to use the ruid2 module to switch the context of some CGI
applications. This set-up has worked fine on Debian oldstable but
after the upgrade the Apache does not work anymore.
In order to track down this issue, I disabled all the
modules and now only the following ones are loaded:
Loaded Modules:
core_module (static)
so_module (static)
watchdog_module (static)
http_module (static)
log_config_module (static)
logio_module (static)
version_module (static)
unixd_module (static)
authz_core_module (shared)
mpm_worker_module (shared)
ruid2_module (shared)
The error log looks like this:

I tried to generate a backtrace from GDB but I was unable to locate
any debug symbols package of mod_ruid2:
