Can you try to remove import gtk; gtk.threads_init() in deskbar-applet, and
replace it by

import gobject
gobject.threads_init()

Maybe that will work, and maybe it will also break everything else..

Comment 2 Mikkel Kamstrup Erlandsen 2005-10-31 18:48:54 UTC

I'm trying it right now... Just waiting for it to crash (if it still does that)

You do realize that this breaks window-mode deskbar..?

Comment 3 Raphael Slinckx 2005-10-31 19:01:33 UTC

No, i didn't try it here. Threads are evil. I hate Threads.

Why is window-mode broken ? is it a freeze ? you can add import gtk, if you
want, but after the import gobject: init() lines

Comment 4 Mikkel Kamstrup Erlandsen 2005-10-31 20:55:41 UTC

It's not broken in any unfixable way... It's just that we need the gtk module to
create the window :)

Adding a "import gtk" in the line 84 "if standalone:" statement should fix it I
think.

Until now, no segfaults since my last post...

Comment 5 Raphael Slinckx 2005-11-04 14:49:31 UTC

I think that is solved ?

Comment 6 Mikkel Kamstrup Erlandsen 2005-11-24 12:25:30 UTC

Since I'm on a crappy public computer, bugzilla is my only mean of 
communication...

I'll just say that I'll be off development a while since my wife and daughter 
(to be born) is commited to hospital. Internet acces is severely restricted 
here, and I have no idea when we'll be out again... It might be up to a 
month :-(

Keep up the happy hacking. I'm really sorry for bugging out on the Cuemiac 
branch this way, but real life is really real sometimes.

See ya 'round.

Cheers
Mikkkel
