bug#39527: Cannot log into LXQt DE

[o . rojon]

Hello everyone,

as the title says, I am (no longer) able to log into the LXQt DE. When I 
first installed it system-wide, I was able to log in. Later, I deleted 
it from my os-config and reconfigured. Later again, I re-added it to my 
os config and reconfigured. Now I have tried a couple of this to deal 
with this:
1) I deleted previous system and profile generations. I used `guix gc` 
to garbage collect. Then I used `sudo guix system reconfigure`. At this 
point in time, I only had the (meta-)package "lxqt" in my os config 
file.
2) I added about every package with a "lxqt"-prefix to the os config 
file and essentially repeated the steps mentioned in 1).

I am not entire certain which informations you will need in order to be 
able to help me. But I guess two things I can easily provide are my 
system configuration and a log of the reconfigure process - the latter 
because during the last reconfigure's, I noticed some things I would at 
first sight classify as anomalies (lines starting with "WARNING"). I 
hope that the german sprinkles in between the log are not all too 
confusing ;-)

If you need anything else, please tell me.
