Package: xfce4-panel
Version: 4.18.2-1
Severity: important
X-Debbugs-Cc: cquike@arcor.de

Since a few weeks, when xfce4-panel was upgraded to 4.18.2-1 (or at least I
don't remember seeing that before), I ocasionally get an irresponsive panel
apparently due to high CPU usage. If I click on anything in the panel nothing
happens until several minutes later.
I have attached a debugger and this is the stak trace I got, in case that might
be useful:

As a workaround, issuing xfce4-panel -r in a terminal seems to eventually
restart the panel and normal behaviour is restored. Although that also takes
several minutes to take effect.
