Segfault when adding custom document properties
From our downstream bug report at https://bugs.gentoo.org/663582
From Vince C.:
Go to File > Document Properties, switch to Properties in the left list, add a custom property name, say "URI", enter anything for the ´Value´ field and press ´Add´: gnumeric crashes. I've tried versions 1.12.35 to 1.12.42 (the most recent at the time of this report). They all crash with a segfault in libgobject-*.so.0 . I've also tried with other property names, with existing documents and an empty document: there's a crash every time.
I've successfully reproduced the problem with a more complete stacktrace.
