You've provided information that we didn't have before, which is never a
waste of time when trying to fix a bug without knowing why it happens...

Hmm. I wonder whether that's significant: one of the other bug reports
with this failure mode was on a Raspberry Pi SD card, and neither USB
sticks nor SD cards are really designed for heavy/long-term use, so
they're probably more prone to corruption than a conventional HDD/SSD.

If they also existed, that's at least consistent... which is maybe
evidence that this *wasn't* caused by filesystem corruption?

Interesting. That means that to have ever had 2.36.x installed, at some
point you must have upgraded to unstable or testing, and then downgraded
back to stable at some later time?
That isn't a supported action (we officially don't support downgrades),
but it also isn't meant to leave stray files lying around like this.

That is itself useful information: it tells me that GLib was the only
(32-bit) library for which this happened to you.
That suggests that there might be something special about GLib, beyond
"has moved from /lib to /usr/lib" (which is consistent with the fact
that we keep getting these bug reports that other library maintainers
mostly don't) - but I have no idea what.
