[Fluxbox-users] XnView crashes Fluxbox 1.1.1

[Michael Piotrowski]

Hi,

I'm using Fluxbox on NetBSD 4.0 (with the default X server, XFree86
4.5.0). I'm compiling Fluxbox myself.

After updating to Fluxbox 1.1.1, I noticed that Fluxbox crashed when
viewing images with XnView [1]--not immediately, but after about four or
five images. This behavior is consistent and reproducible for me.

I checked out the latest version from git, and the problem is still
there. I then went back to Release-1_1_0_1, which does not have this
issue.

So, apparently, something changed between Release-1_1_0_1 and
Release-1_1_1, which causes these crashes.

I don't have the time to do much debugging myself
(must-work-on-dissertation!), but I'd be willing to help and could build
a debug version and provide a core dump, for example.

Thanks and greetings


Footnotes:
[1] <http://xnview.com/>, I'm using version 1.68, the latest version
available for NetBSD.

try out the latest git version.

% git clone git://git.fluxbox.org/fluxbox.git
% cd fluxbox
% ./autogen.sh
% ./configure
% ./make

and then just try running the src/fluxbox binary.

does that still crash?

cheers,

No, it doesn't. Great, it seems you fixed the problem!

Thanks for your quick response and the fix, and thanks to everybody on
the Fluxbox team for a great window manager!

No, it doesn't. Great, it seems you fixed the problem!

just last check: your netbsd runs on 64bit?

No, I'm using 32-bit builds of NetBSD (i386 on "real" hardware and on
VMware Fusion).

I just checked <http://git.fluxbox.org/>, and I'm a bit confused now: I
build git HEAD on October 17 and observed the same problem. The Fluxbox
I built today (GIT Revision: 3b9611b61ddc023225092a85b21867131fb363cc)
works fine. I now see that there was only a minor change ("increase
default size of toolbar and icon buttons") since October 17. But this
was probably a mixup of versions on my part.

oha, interesting. then i would have no real explanation for your
"solved problem" atm. we had some crashes on "bad" apps feeding "bad"
_NET_WM_ICON data to fluxbox. eg, xnview shows a tiny "preview" in the
icon of the window. that would change after each new image.

so at the moment you dont see any problems anymore?

Hmm, I see. But XnView doesn't change its icon, AFAICS. So, yes, it's
somewhat strange.

Umm, I just had a crash when I wanted to verify it ;-)

However, before that I viewed hundreds of photos today without problems,
so it is definitely pretty stable now and I can't reproduce crashes at
will.

I'll use this revision for a few more days and we'll see how it
behaves. I'll report back when I experience any problems.

Thanks and greetings
