This is the type of thing that we're no longer likely to see very much
in Pidgin because glib >= 2.18 (IIRC) will no longer crash.
You might want to look into upgrading the version of glib that you're
shipping to something more recent (we're currently using 2.20.5).
It certainly is still considered a "bug" to pass NULL to printf, so if
you figure out any specific causes, of course we'll be happy to fix

I'm pretty sure the commit associated with #12387 will address this crash.
