Otherwise LGTM!

DAMN. Merge conflicts, from right now.

I resolved the conflict

Result of nixpkgs-review pr 106742 run on x86_64-linux 1

9 packages built:

• bibletime
• dfilemanager
• herqq
• merkaartor
• mindforger
• seafile-client
• seafile-shared
• solarus
• solarus-quest-editor

No unfunctional executables besides:

(ins)[nix-shell:~/.cache/nixpkgs-review/pr-106742-1]$ ./results/seafile-shared/bin/seaf-cli --help
Traceback (most recent call last):

    from pysearpc import searpc_func, SearpcError, NamedPipeClient
ModuleNotFoundError: No module named 'pysearpc'

Which is not a regression as a similar error happens on master:

Traceback (most recent call last):
  File "/nix/store/pihq9hv0knyw7rvlb6cvmf91iniyva0a-seafile-shared-7.0.10/bin/.seaf-cli-wrapped", line 93, in <module>
    import urllib.request, urllib.parse, urllib.error
ImportError: No module named request

I'm merging since this is an improvement for all packages involved, and no worse situation for seafile-shared.

Oh sorry, didn't see this situation, but as you say, the problem seems unrelated to qt
