which leads to a null pointer dereference in this case.

This seems to be a regression in glib, which used to support passing an
empty argv:

[Jackson Doak (noskcaj)]

There is a new upstream release shown on the website. that might fix this

[Andreas Moog (ampelbein)]

This is fixed in the current Ubuntu development release.
