Xfce4-panel dissapears (segfault)

Question

I'm using xfce4-svn. The latest xfce4-panel-svn, 4.5.0.3svn-r26171, segfaults, leaving me without panels. GDB shows this:
Program received signal SIGSEGV, Segmentation fault.
0xb7ec679d in xfce_arrow_button_set_arrow_type ()
   from /usr/lib/libxfce4panel.so.1
Sorry if it was already reported, I searched bugs at xfce bugzilla and arch flyspray and found nothing. Just wanted to confirm if it happens to someone else. Already tried deleting ~/.config and starting xfce using another user, without luck.
Plus, before my panel started sefgaulting, I had the same problem of my xfce menu dissapearing.
I'm the only one?

I had the same problem and after googling for awhile I found a workaround that seems to work to only have one panel on your xfce4 desktop.  It seems that you have to go ahead and delete either panel in the desktop manager.  It doesn't matter which as both panels (top and bottom) will disappear.  Then edit your ~/.config/xfce4/panel/panels.xml file to remove one panel's info from <panel> to <panel>.  This is what you're left with:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE config SYSTEM "config.dtd">
<panels>
<panel>
<properties>
<property name="size" value="27"/>
<property name="monitor" value="0"/>
<property name="screen-position" value="10"/>
<property name="fullwidth" value="1"/>
<property name="xoffset" value="0"/>
<property name="yoffset" value="996"/>
<property name="handlestyle" value="0"/>
<property name="autohide" value="0"/>
<property name="transparency" value="25"/>
<property name="activetrans" value="0"/>
</properties>
<items>
<item name="xfce4-menu" id="5"/>
<item name="separator" id="6"/>
<item name="launcher" id="10"/>
<item name="launcher" id="11934103341"/>
<item name="launcher" id="11934284041"/>
<item name="actions" id="12"/>
<item name="separator" id="11934162861"/>
<item name="tasklist" id="11934220980"/>
<item name="datetime" id="11934096510"/>
</items>
</panel>
</panels>
Save the file and logout of xfce4. NOTE: Make sure you don't have the "save session" box checked off when you log out or all is for not.  When you log back in, voila, only one panel.
