It's an environment issue. Environment.internalGetHome() is mapped in mono/mono/metadata/icall.c to ves_icall_System_Environment_InternalGetHome(), which does:
return mono_string_new (mono_domain_get (), g_get_home_dir ());
g_get_home_dir() is defined in mono/eglib/src/gmisc-unix.c.
mono_string_new() is defined in mono/mono/metadata/object.c, and does:
mono_string_new (MonoDomain *domain, const char *text)
l = strlen (text);
Note: strlen(NULL) aborts.
Deduction: g_get_home_dir() is returning NULL, which aborts in the strlen() call. You'll need to figure out why g_get_home_dir() is returning NULL, and/or how to work around it.
