This *is* the offending commit, as far as I understand. Merely rebased in=

linux-stable, and hence having a different SHA, but mentioning the origin=
al SHA
(i.e., 532b0f7ece4c) in its commit message.

Okay, these two are not part of 5.1.5. I've backported them (and only the=
se two)
to 5.1.5 and the issue(s) seem to be gone. Definitely something that shou=
ld be
backported to/included in 5.1.6.


Thanks for pointing all that out! Unfortunately I didn't add anything use=
ful but
noise, since you obviously already knew, that this commit was broken. I'd=
 urge
Greg to release a new stable version including the fixes soon, if possibl=
e,
though, for not being able to start/use userspace browsers sounds like a =
pretty
bad regression to me.
