Hi,

I did a safe-upgrade, which upgraded nvidia-graphics-drivers to 280.13-2, and after reboot, X didn't 
start (properly).
In /var/log/Xorg.0.log I found a/the message about mismatching ABI version. 
Since I'm subscribed to this list, I was aware of a potential problem (hence the reboot) and 
therefor was able to quickly find the relevant bug report (639737).
That bug report describes how to fix/workaround it ('therefore the "IgnoreABI" option needs to be 
enabled, see xorg.conf(5)'). (Haven't tried if it worked yet)
I do have apt-listbugs installed, but since this bug was/is severity normal (and marked as done)
I didn't get a warning or sth like that.
I got X working again by downgrading (and holding) to the testing versions of nvidia-kernel-dkms and 
xserver-xorg-video-nvidia which caused those and related packages to be downgraded:

partly snippet from /var/log/aptitude:
=================================================================
[DOWNGRADE] libgl1-nvidia-glx 280.13-2 -> 280.13-1
[DOWNGRADE] nvidia-alternative 280.13-2 -> 280.13-1
[DOWNGRADE] nvidia-glx 280.13-2 -> 280.13-1
[DOWNGRADE] nvidia-vdpau-driver 280.13-2 -> 280.13-1
[DOWNGRADE] xserver-xorg-core 2:1.11.0-1 -> 2:1.10.4-1
[DOWNGRADE] xserver-xorg-input-evdev 1:2.6.0-2+b2 -> 1:2.6.0-2+b1
[DOWNGRADE] xserver-xorg-video-nvidia 280.13-2 -> 280.13-1
[DOWNGRADE] xserver-xorg-video-vesa 1:2.3.0-7+b1 -> 1:2.3.0-7
[HOLD] nvidia-kernel-dkms
=================================================================

But if I wasn't subscribed to this list, I probably wouldn't have found this bug report and therefor 
wouldn't have found the workaround.
And since this bug is closed and doesn't (didn't) have a high enough severity, apt-listbug didn't 
issue a warning that the upgrade would make X stop working and/or alerted me to the bug report 
describing the workaround.

Shouldn't there be a warning or sth like that mentioning the workaround when upgrading to 280.13-2?
And/or shouldn't this bug be reopened (or sth like that) with a higher severity, so ppl with apt-
listbug will get notified and prevents the current version from entering testing?
