Bug#743566: [Pkg-mc-devel] Bug#743566: mc: Failed gpm connect attempt
This bug just crashed my system by generating 2.2 GB of logs and caused a day of debugging - exactly when I needed to leave for a week.
Bug#743566: mc: Failed gpm connect attempt
Control: severity critical -1
I think this bug should be bump to cricical. mc burn my cpu. Simple
patch from last answer fixes the problem and it should be added to
jessie version.
Also I attach my nmu debdiff.

There is no need to re-(set) severity level to a dramatically incorrect value -- see https://www.debian.org/Bugs/Developer#severities I think this bug should be bump to cricical. mc burn my cpu. Thanks. Maintainer may decide to reconsider severity level however at the moment he believes that correct severity level is important. Simple patch from last answer fixes the problem and it should be added to jessie version. I'm not convinced that this patch is the correct solution to the problem. We will follow upstream decision on this. Earlier I gave my analysis of the problem in http://www.midnight-commander.org/ticket/3208#comment:1 where I've noted that setting TERM=xterm may be easier workaround than patching. It may be helpful if you remind upstream how important this problem really is. Also I attach my nmu debdiff. Thank you but I must say that considering late freeze a correct NMU should contain one and only one isolated fix addressing this particular problem.

Bug#743566: mc: Failed gpm connect attempt
It should work with mouse if gpm package is installed... Also this functionality depends on value of TERM environment variable. See details in the upstream ticket: http://www.midnight-commander.org/ticket/3208 It _should_ work, but _does_ it work? I cannot make it work in console, in both wheezy and jessie, regardless of $TERM. I have gpm and screen installed, I login in, say, tty1, and do screen mc - it doesn't respond to mouse.

Hi Jakub, I'd like to reproduce the problem but nothing like this is happening here in `screen` or `tmux` (I don't have package gpm installed). Do you think it might be a regression?
