Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
X-Debbugs-Cc: kwin@packages.debian.org, hefee@debian.org
Control: affects -1 + src:kwin
Please unblock package kwin
[ Reason ]
Fix 1033212. For limba phones kwin is not usable at all, with that fix
it is usable again.
[ Impact ]
Plasma mobile is not usable on limba phones.
[ Tests ]
Marco Mattiolo, the author of the patch for kwin, tested it on their
devices.
[ Risks ]
The patch is very simple and straightforward. For me it seems not very
likly that it has bad outcome for other users. On experimental there is
also kwin 5.27.3 with that patch included and that is also tested be a
bunch of people.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
[ Other info ]
You do a great work and you are very fast responding ;)
