Subject: wmii freeze exception
Hello,
There's a nasty bug in wmii, #628575. It's already fixed upstream, and
it's already packaged by me, but that version is certainly unsuitable
for current release so given short enough timeframe I didn't bother
trying to upload it to unstable via my sponsor. However, I've
backported the patch for this particular bug, so users of 3.9.2 can
have it fixed.
Basically, the fix is to add some NULL pointer checks, plus some
changes in boundaries calculations. It's been tested quite extensively:
I've been using patched wmii every day for a whole year without any
troubles. A debdiff is attached, a .dsc can be found here:
http://mentors.debian.net/debian/pool/main/w/wmii/wmii_3.9.2+debian-4.dsc
Please review it an tell me if it fits to be uploaded to unstable with a
freeze exception for wheezy/testing.
P.S. Please Cc me as I'm not subscribed to this list.
