lxappearance-obconf plugin causes lxappearance 0.6.1-1 to segfault

[A. Eibach]

I just don't understand it.
Towards 0.2.2-1, lxappearance-obconf plugin 0.2.2-2 only seems to have undergone a cosmetical change (i. e. information update).

But lxappearance 0.6.1-1 works perfectly with 0.2.2-1 here on Wily.

(Using Openbox 3.5.2-8.)

However lxappearance 0.6.1-1 with plugin version 0.2.2-2 makes it crash!
So if you can reproduce the crash, LEAVE lxappearance at its latest version and only do a minimal downgrade of lxappearance-obconf! It's the plugin that literally forces lxappearance main program into the segfault abyss.

SUCCESS!

Managed to "fix" it myself.
However, I had to install openbox 3.6.0 first (yet marked unstable) and the new dependencies (since lxappearance-obconf 0.2.2.3) libobrender31 and libobt4.

Works now, but should not be closed, as openbox 3.6.0 is still a little "futuristic" ;)

Openbox 3.6 is about to hit wily, and with it a newer lxappearance-obconf.
Just wait a few days and this should fix itself

3.6 in wily? That's a great news, thank you!!

[A. Eibach (andi3)]

Got it! Just uploaded about 10 hours ago.
However, after enabling wily-proposed for openbox in /etc/apt/sources.list, I had to use

$ sudo apt-get dist-upgrade

since the ordinary "upgrade" option did not install the new openbox.

Status changed to 'Confirmed' because the bug affects multiple users.

[Launchpad Janitor (janitor)]

This bug was fixed in the package lxappearance-obconf - 0.2.2-3build1

---------------
lxappearance-obconf (0.2.2-3build1) wily; urgency=medium

  * No change, rebuild against openbox 3.6.1 (LP: #1469276)
