tracker-extract-3 crashes routinely during distribution upgrades

[Skia]

Very similar behavior as this existing bug: https://bugs.launchpad.net/ubuntu/+source/tracker-miners/+bug/1983859

Almost copy-paste of original report:

When upgrading Ubuntu Desktop from 22.04 to 24.04, there's often (pretty much always) a crash from tracker-extract, as described in the following error report:

https://errors.ubuntu.com/oops/7a86fbf0-b52b-11ee-b9e4-fa163e171f02

The crash occurs during the upgrade, which means it's fairly hard to investigate exactly what's going on as apport fails to extract a stack trace, the binaries being overwritten during the upgrade.

Here is a quick `gdb` session showing the poor backtrace that I got: https://pastebin.ubuntu.com/p/GqXxw9xGzc/

This is failing to retrace due to the fact that there are mixture of packages from Noble and Jammy. It'd be interesting to look at the timestamp of the crash versus where we were in the upgrade process but I suspect it was somewhere in the middle. Subsequently, I think we should probably just turn off whatever runs tracker-extract while the upgrade is in progress. (There is code in ubuntu-release-upgrader to do similar things.)

Here's part of apport's output:

Or we could ignore crashes from tracker-extract-3 as done in this merge proposal.

Looking at the upgrade log the crash occurred around these package operations:

This bug was fixed in the package ubuntu-release-upgrader - 1:24.04.11

---------------
ubuntu-release-upgrader (1:24.04.11) noble; urgency=medium

  * test: fix typo assertEqaul (LP: #2059784)
  * Run pre-build.sh: updating mirrors, demotions, and translations.
