Comment 5 for bug 385704

This may caused by another bug reported in Debian, about Mono not following symbolic links for some things:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=500799

Any chance your /usr, /lib/, or /etc are symbolic links?

Either way, it would be helpful if you could run the following command:

strace -e trace=file tomboy &> trace.out && grep "/config\"" trace.out

Use ctrl+c to quit it after running for a second or two, then paste the output here. Mine looks like this:

$ strace -e trace=file tomboy &> blah.out && grep "/config\"" blah.out
^Copen("/etc/mono/config", O_RDONLY|O_LARGEFILE) = 3
open("/home/sandy/.mono/config", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/etc/selinux/config", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)

I'm curious where yours is looking *instead* of /etc/mono/config.
