Hi,

in this report are 2 independent issues, one leads to the other.

The postinst maintainer script of mono-gac fails to configure because
/usr/bin/gacutil crashes in /usr/bin/mono which is the mono runtime,
thus I am reassigning and retitling.

This crash is a very serious issue as it basically prevents you from
running any tool or application that uses the mono runtime. At the same
time it will leave your package management system (apt/dpkg) in a very
bad state behind.

To get a better picture where exactly the issue pops up, please install
the debug symbols of mono by using:
apt-get install libmono0-dbg mono-runtime-dbg

If that fails to install, try it using dpkg -i

Then run "gacutil -l" which should segfault but hopefully this time with
source line information.

As the stacktrace looks like the issue is related to shared memory which
is kept in /dev/shm, please make sure it is correctly mounted and
possibly shows some files in that location.

I would really like to get this issue solved in time for squeeze, but I
am unable to reproduce it, so I need your help to track it down.

PS: If you are still able to reproduce this issue it would probably help
if you could join me on IRC in the #debian-cli channel found on the OFTC
network.
