Comment # 2 on bug 907545 from Reinhard Max

I finally got around to work on this and found a much shorter example to
reproduce it:

--- snip ---
#!/usr/bin/tclsh

package require TclCurl

set multiHandle [curl::multiinit]
set easyHandle  [curl::init]
$multiHandle addhandle $easyHandle
$multiHandle removehandle $easyHandle
--- snap ---

In this example the segfault happens at a different place in the code, but the
underlaying problem seems to be the same, which is a null pointer dereference
in a linked list element.
