Hello Sam,

>I haven’t heard a bug like this reported, but there is a bug in SDL 2.0.6 dbus handling.

if you refer to the dbus calling patch, I already backported this in the latest -3 upload,
and if the regression went from -2 to -3 (not 2.0.6 in general), this is probably the
culprit for the regression, or the CVE fix)

see the changelog:
[ Gianfranco Costamagna ]
* debian/patches/dc7245e3d1f2.patch:
- backport upstream fix for dbus error.
LP: #1721907
thanks LGB [Gábor Lénárt] (lgb) for the report!
[ Felix Geyer ]
* Fix CVE-2017-2888: Integer overflow while creating a new RGB surface.
- Add d/patches/CVE-2017-2888.patch
- Closes: #878264

so, if we confirm the -3 upload is the first "bad", we need to dig into the CVE patch
or the dbus error one
