With the recent upload of GLib 2.62 to unstable, poppler's autopkgtest has
started failing:

GTime is a gint32 (not a time_t, although it happens to be equivalent on
older 32-bit architectures) counting seconds since the beginning of 1970.
As such it is not Y2038-safe. It has been informally deprecated for
a while, but GLib only recently added support for marking types as
deprecated in a machine-readable way.

The deprecation warnings can be disabled for code that depends on
poppler by wrapping a block with the G_GNUC_BEGIN_IGNORE_DEPRECATIONS
and G_GNUC_END_IGNORE_DEPRECATIONS macros, similar to this gconf patch:

I'll prepare a patch and send it upstream.
