I'm trying polari. Whenever I try to connect to any network, the UI says
the connection failed, and the user journal shows this:

nov 21 14:07:27 ava org.freedesktop.Telepathy.ConnectionManager.idle[11724]: /usr/lib/telepathy/telepathy-idle: error while loading shared libraries: libdbus-glib-1.so.2: failed to map segment from shared object

I can reproduce this easily in a shell as well:

$ /usr/lib/telepathy/telepathy-idle --help
/usr/lib/telepathy/telepathy-idle: error while loading shared libraries: libdbus-glib-1.so.2: failed to map segment from shared object

This is an arm64 system. I tried to reproduce it on an amd64, before
upgrading, and couldn't - telepathy-idle would start without problem.
After upgrading and rebooting, I could then reproduce the same problem.
Very few packages in this last upgrade seemed to be probably cause for
this. As there was a kernel upgrade, I tried rebooting into the old
kernel (6.16), and then I could not reproduce the issue anymore.

I'm reporting this against linux because other packages using
libdbus-glib (e.g. hexchat) work just fine.
