CI failure: glib:gio+slow / gdbus-export killed by SIGSEGV

This is almost certainly not enough information to do anything useful with, but I'm opening the issue now so that if we see this again, we'll have an idea of how often it happens.

Job #590620 failed for 2b863856:

196/270 glib:gio+slow / gdbus-export            FAIL     0.37 s (killed by signal 11 SIGSEGV)
