+Subject: eg-sampler: Fix segfault on old_sample null deref
+
+Fixes a segmentation fault in eg-sampler when a sample is loaded for the first
+time. Dereferencing old_sample->path causes the NULL pointer segfault.
+
+Resolved by always simplifying code to always write_set_file,
+even if the filename is the same.
