In fact, it is not a bug in lxpanel, but rather two other bugs:
1) the file /usr/share/applications/unity-lens-photos.desktop (from package unity-lens-photos) is invalid as it does not contain mandatory Exec line;
2) the libfm (from package libfm4) does not check for missing Exec key and therefore crashes.
The upstream of libfm is notified about the crash, see https://sourceforge.net/p/pcmanfm/bugs/953/ bugreport.
