Exception on configuration if old version of log4net is present

In my project i use a library that was built on .net 2.0 with old log4net.
On NHibernate configuration it throws exception:

at System.Reflection.Emit.InternalAssemblyBuilder.get_Location()
at log4net.helpers.SystemInfo.AssemblyLocationInfo(Assembly myAssembly)

Could you load default LoggerFactory in such a case or throw reasonable exception.

Thnks.
