Dear Zheng Thank you for your hard work bringing KDE to Guix. It is not the best circumstance to express my gratitude, but I want you to know I am grateful before anything else.
With commit 2f407ac162d6b9053bafb611ff20b58b13e7a09c to guix, you have modified the testing phase of kmime build, which I currently suspect as the reason for the inability to reconfigure my systems. I also suspect the recent merge of core-updates could have caused this breakage. For your convenience, here is the link to the bug report: https://issues.guix.gnu.org/73067 It contains the build output narrowed to the check phase. Do you think this could be at least worked around relatively quickly? I will do my best to assist with the review process.
