Closed issue by oreo639 on void-packages repository

https://github.com/void-linux/void-packages/issues/36734

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  Void 5.15.32_1 x86_64 GenuineIntel uptodate hold rrrmFFFFFFFFFFFFFFFF
  *output of ``xuname`` (part of xtools)*
* package:  `kitinerary-21.12.3_1`
  *affected package(s) including the version*: ``xbps-query -p pkgver <pkgname>``

### Expected behavior
Tests succeed when performing:
`./xbps-src check kitinerary`

### Actual behavior
`Test #31: calendarhandlertest` fails due to the ics file generated not entirely matching what was expected. (most of the differences are just caps instead of lower case or extra information)
Here is a log of the full output:
https://github.com/void-linux/void-packages/runs/6053085034?check_suite_focus=true
(in the log above the issue occurred in the poppler PR, but I can reproduce this issue in the master branch even after clearing out the builddir)

### Steps to reproduce the behavior
`./xbps-src check kitinerary`

Not sure how best to fix this. (the best I can think of would probably be to just disable the tests until the next release)
