I can confirm that the above upstream commit fixes the problem
(and applies cleanly to the debian version). Would be great if
you could include it in your next upload.

+Subject: platform: fix crash hashing NMPlatformTfilter and NMPlatformQdisc
+
+@kind might be NULL. There are 3 forms of the hash-update functions for
+string: str(), str0(), and strarr().
+
+- str0() is when the string might be NULL.
+- str() does not allow the string to be NULL
+- strarr() is like str(), except it adds a G_STATIC_ASSERT()
+ that the argument is a C array.
+
+The reason why a difference between str() and str0() exists, is
+because str0() hashes NULL different from a "" or any other string.
+This has an overhead, because it effectively must hash another bit
+of information that tells whether a string was passed or not.
+
+The reason is, that hashing a tupple of two strings should always
+yield a different hash value, even for "aa",""; "a","a"; "","aa",
+where naive concatentation would yield identical hash values in all
+three cases.
