Graham, do you think this is the same as bug 1354961?

[Mazen (mezen)]

maybe but in my case, nedit doesnt run anyway, the crash was immediate.

[Paul Gevers (paul-climbing)]

Seems like this is a duplicate of 1415309.

Are you by any chance also running lubuntu?

[Mazen (mezen)]

No, I am running ubuntu gnome-session-flashback

CurrentDesktop: GNOME-Flashback:Unity

@Paul:
> Graham, do you think this is the same as bug 1354961?
I don't think so, but it should be easy to test.

@Mazen: can you install Motif from my PPA below please and see if it makes a difference?
https://launchpad.net/~ginggs/+archive/ubuntu/motif1565

I haven't been able to get Nedit to crash yet. I have tried unity and gnome flashback (compiz and metacity).

[Mazen (mezen)]

@Graham:
I installed motif from this ppa "ppa:ginggs/motif1565" but the issue remains the same.

$ dpkg -l | grep motif
ii libmotif-common 2.3.4-8~ppa4 all Motif - common files

$ nedit
Erreur de segmentation (core dumped)

[Graham Inggs (ginggs)]

@Mazen: Thanks for confirming.

[Mazen (mezen)]

Just in case, I solved the problem by creating a file ~/.Xdefaults where I put this line

$ cat .Xdefaults
*font: -*-dina-medium-r-*-*-16-*-*-*-*-*-*-*

No crash for nedit this time.

When I remove the file ".Xdefaults" or rename it to something else, nedit segfaults.This seems like nedit cannot find the default fonts...

I believe it's hard to say that this problem is due to a single issue. For me, nedit successfully upgraded on 2 machines going from 15.10 -> 16.04. But i saw the segfault on a VM created from scratch. I observed that ~/.nedit was unpopulated -- no nedit.rc.

My solution was to place a copy of nedit.rc from a working machine into ~/.nedit in the VM. After that, things were good.

On your system from scratch, do you have xfonts-100dpi or xfonts-75dpi
installed as recommended by nedit?
