[Aurelien Jarno <aurel32@debian.org>]

Source: lomiri-thumbnailer

Dear maintainer,

lomiri-thumbnailer used to sometimes fail on the buildd due to testsuite
failures. The recent version seems to make things worse, with the
testsuite always failing:

| 96% tests passed, 1 tests failed out of 26
|
| Total Test time (real) = 719.31 sec
|
| The following tests FAILED:
| 	 21 - stress (Failed)
| Errors while running CTest
| make[2]: *** [Makefile:74: test] Error 8
| make[2]: Leaving directory '/build/reproducible-path/lomiri-thumbnailer-3.0.5/obj-riscv64-linux-gnu'
| dh_auto_test: error: cd obj-riscv64-linux-gnu && make -j1 test ARGS\+=--verbose ARGS\+=-j1 ARGS=\"--verbose\" returned exit code 2
| make[1]: *** [debian/rules:49: override_dh_auto_test] Error 25
| make[1]: Leaving directory '/build/reproducible-path/lomiri-thumbnailer-3.0.5'
| make: *** [debian/rules:21: binary-arch] Error 2
| dpkg-buildpackage: error: debian/rules binary-arch subprocess returned exit status 2

A full build log is available here:
https://buildd.debian.org/status/fetch.php?pkg=lomiri-thumbnailer&arch=riscv64&ver=3.0.5-1&stamp=1759736831&raw=0

I tracked that down to timeouts that are a bit to tight for our build
machines.  The following patches fixes the issue:

Note that the thumbnailer test didn't fail in the build log above, but
is also a bit flaky, and some other builds logs show it failing.
