Right click an icon 2. Choose "Move" 3. Place the icon anywhere on the panel Actual Results: Segfault. Expected Results: The icon should appear where the user moved it.

Created attachment 169887 [details] GDB backtrace
Created attachment 169889 [details] Gzipped strace output I ran strace on the process, and immediately caused it to segfault via the procedure explained in the bug report.
your backtrace is useless, please take a look at http://www.gentoo.org/proj/en/qa/backtraces.xml and retry with 4.4.3
I was trying to avoid recompiling my entire system if the problem (or at least, the solution) was obvious -- it looked even worse before the GDB patch. Anyway, xfce4-panel-4.4.3 works; thanks.
