Xfce4.4 panel "Segmentation fault" when trying to add items
Hey guys,
First of all, thanks for the 4.4 release! Very, very cool.
I grabbed the installer package from the site and everything went smoothly during compilation and install. I have not changed anything; I simply installed and restarted X. Also, I should add this is a brand new, fresh install of Slackware 11.0. The only thing updated on the distro is the kernel (which I am now running 2.6.17, and it's fairly bloated).
EDIT: These are the versions of other software I have installed (I'm not sure which are applicable to my problem):
gcc-3.4.6
glib-1.2.10
glib2-2.10.3
glibc-2.3.6
gtk+-1.2.10
gtk+2-2.8.20
Now, after Xfce and all related apps have been loaded, the desktop looks fine. No problems. When I right click on one of my 2 panels and choose "Add items...", the panel suddenly crashes. I recompiled the panel with --debug=full (or whatever) and reinstalled it, but it's still crashing. Here's the output when run from a terminal:

Re: Xfce4.4 panel "Segmentation fault" when trying to add items
Can you create a backtrace in gdb? (gdb xfce4-panel -> run -> wait for crash -> bt)

Re: Xfce4.4 panel "Segmentation fault" when trying to add items
I have created a bugzilla report for this, so I won't forget: http://bugzilla.xfce.org/show_bug.cgi?id=2933 .
I don't immediately see what is wrong here, but I haven't really looked at the code yet. Thanks for letting us know.

Thanks for adding the report.
Can't wait to start using the panel! Alt+Tab will have to do for the time being. :razz:

Re: Xfce4.4 panel "Segmentation fault" when trying to add items
It would be nice if you could try this patch:
http://www.loculus.nl/xfce/files/tree-selection.patch
I'm hoping it will solve the problem, but I need someone to test it.

Re: Xfce4.4 panel "Segmentation fault" when trying to add items
Wonderful! That worked perfectly.
For anyone else reading this with the same problem:
After recompiling and installing, the plugins were still not showing up in the "Add items" dialog. This was because my permission scheme wasn't allowing me access to the '/usr/share/xfce4/panel-plugins' directory.
I just simply `sudo chmod 755 /usr/share/xfce4/panel-plugins` and everything was good as new.
Thanks a lot, guys, and keep up the good work!

Re: Xfce4.4 panel "Segmentation fault" when trying to add items
Thanks a lot for testing. I have closed the report and the next update for Xfce should contain the fix.
