Comment 4 for bug 1750741

Seyeong,

+ - d/p/0001-GDBusProxy-Fix-a-memory-leak-during-initialization.patch

this fixes a memory leak, but in later code than the Trusty glib2.0 code

+ - d/p/0001-tests-gdatetime-Use-a-real-rather-than-invented-time.patch

this fixes an autopkgtest regression, that's unrelated to this memleak bug - it's ok to include in the same upload, but it needs its own lp bug. This is also needed in xenial glib2.0.

+ - d/p/0001-gio-Add-names-to-idles-and-timeouts.patch
+ - d/p/0002-gio-belatedly-port-gdbus-from-GSimpleAsyncResult-to-.patch

these patches are huge backports, that update the glib2.0 code to use a different function that appears to *introduce* the memleak that your first patch "fixes". Are you sure there is actually a memleak in the Trusty glib2.0 code? If so, it does not seem to be the one that your first patch fixes. In any case, this huge backport is not acceptable as a SRU for only a memleak.
