Window List applet conflicts with Wolfram Mathematica 5.x

[leon]

Mathematica cause gnome-panel no response to mouse click and so on.
Top command shows /usr/lib/gnome-panel/wnck-applet using almost 100% CPU.

Thanks for your bug. I'm changing the setting because mathematica is not shipped
by ubuntu. What version of the distribution do you use? Can you get a backtrace
of the hang with libgnomevfs-2-dbg and gnome-panel-dbg installed? You can use
that to get it:
- gdb -p `pidof wnck-applet`
(gdb) thread apply all bt

Could you remove the windows list and the desktop switcher applet to note which
one do this?

Window List applet conflicts with Mathematica 5.x.
Every application window doesn't show up in the window list applet after
starting mathematica.

Thanks for the backtrace. There is a bug upstream about this:
http://bugzilla.gnome.org/show_bug.cgi?id=316096, I've put a comment with your
backtrace on it

[Vincent Untz (vuntz)]

Sebastien: could you make a libwnck-dbg package so that we can have more
informations?

[Mike Wimmer (mike-wimmer)]

I'm experiencing the same bug with Mathematica 4.2. I know that Mathematica does
not ship with Ubuntu, but still it's a rather important program for Linux. Is
there anything I can do to help debugging the problem?

[Sebastien Bacher (seb128)]

out of sending a patch not really, but thanks. I've pinged upstream again.

[Juan Pablo Mendoza (jpablo-gmail)]

A workaround is starting Mathematica using -noSplashScreen. This would prevent
the splash screen to show up (looks like the splash is the window causing trouble).

By the way Mathematica 5.0 doesn't work in ubuntu out of the box for me, becuase
of the change of location of XKeysymDB and X11 locales (to /usr/share/X11).

That's 1) a separate issue, which should be adressed in another bug and 2)
something for Mathematica Upstream to fix.

[Sebastien Bacher (seb128)]

fixed upstream

[Scott James Remnant (Canonical) (canonical-scott)]

No upload yet?

[Danson Joseph (nosnad)]

Use "mathematica -noSplashScreen"
It's the splash screen that causes problems

Cheers,
