Comment (by QuLogic):

 Here's a copy of the patch ungzipped. You need to apply my slightly
 modified 02 patch from #5639 first.

 I fixed an error in im.c where `purple_debug` should have been replaced
 with `qq_hex_dump`. Also, `arg_s` was leaked in `qq_hex_dump`. Finally, I
 left out the changes to packet_parse.c because my 02-patch is already
 correct. FYI, to specify pointers to printf-like format strings, use the
 %p specifier.
