--- Comment #1 from Roland Knall <roland.knall@xxxxxxxxxxxxxxxxx> 2011-03-15 07:59:39 PDT ---
Sitting on a 64-bit Ubuntu, this is how the error occurs.

1. Load latest SVN build
2. Load pcap capture
3. Filter for "malformed" -> apply
4. Go down the packet list with the cursor to the last entry
5. Go up one entry -> crash

kind of funny. Backtrace with gdb shows (full bt attached):
